+atop (2.2.6-3) unstable; urgency=medium
+
+ atop does some really weird things with logrotate, which cause
+ undocumented behavior in logrotate versions < 3.11. As Debian stretch
+ has 3.11, this should not be an issue when updating between stable
+ versions.
+
+ If you have been using unstable or testing, and you get weird
+ messages from logrotate, it might be worth looking in /var/log/atop
+ for weird log files, and removing all dummy_* files other than
+ dummy_after and dummy_before.

+atop (2.2.6-2) unstable; urgency=medium
+
+ PID file /run/atopacctd.pid not readable (yet?) after start
+
+ This is an issue when upgrading from one of the experimental atop
+ versions that have never been in Debian unstable. I therefore don't
+ consider it a bug. The issue is already reported (#842136, #849138).
+ Please don't file additional bug reports for this issue.
+
+ Here is an explanation from upstream (quoting Gerlof with his kind
+ permission):
+
+ |(…), I think that this caused by the fact that the previous run of
+ |atopacctd did not terminate properly. That causes the fact that
+ |files and directories are not removed by atopacctd, giving problems
+ |with the next activation.
+
+ |Obviously, it is possble to remove these files and directories
+ |*during* the next activation (instead of terminating with an error
+ |message). However, I don't want to do that since the existence of
+ |the /run/pacct_shadow.d directory might also indicate that the
+ |atopacctd daemon is already running (then a second incarnation
+ |should refuse to start).
+
+ |So when the issue is solved that atopacctd refuses to terminate (…),
+ |the issue of the existing /run/pacct_shadow.d directory should also
+ |be irrelevant IMHO.
+
+ When atopacctd receives signal 2, 3 or 15, it finishes and destroys
+ the files/directories it has created. If you encounter the situation
+ that atopacctd does not start because it complains about pidfile
+ and/or /run/pacct_* directories/files, please send SIGTERM to any
+ atopacctd process that may still hang around, and if the
+ files/directories are still there without the corresponding atopacctd
+ process, please remove them manually and then try starting atopacctd
+ again.

+atop (2.2.6-2) unstable; urgency=medium
+
+ KERNEL ISSUES WITH PROCESS ACCOUNTING
+
+ Newer upstream kernels have two issues with process accounting.
+ These were isolated and debugged in #833997
+
+ 1) Sometimes process accounting does not work at all¹. Atopacctd tries to
+ work around this issue, by retrying to initialize process accounting
+ several times.
+
+ 2) When using the NETLINK interface, the command TASKSTATS_CMD_GET
+ consequently returns -EINVAL². Atopacctd needs NETLINK to be able to
+ be triggered that some process in the system has finished. In this way
+ atopacctd can be in a blocking state as long as no processes terminate.
+ When atopacctd detects this condition it thus switches into a polling
+ state to periodically try if it can read process accounting records as
+ a workaround. This issue has to do with cpumask and you can work-around
+ it by building a kernel that has CONFIG_NR_CPUS configured to exactly
+ the amount of CPUs (logical CPUs) in the system the kernel runs on. You
+ can find this kernel option under "Processor type and features" -->
+ "Maximum number of CPUs".
+
+ [1] Bug 190271 - process accounting sometimes does not work
+ https://bugzilla.kernel.org/show_bug.cgi?id=190271
+
+ [2] Bug 190711 - Process accounting: Using the NETLINK interface,
+ the command TASKSTATS_CMD_GET returns -EINVAL
+ https://bugzilla.kernel.org/show_bug.cgi?id=190711

+

+ * atop's log file format in /var/log has changed. Old log files will
+ be moved away on upgrade so that the new atop will actually start.
+ * currently the restart of atop does not work because in some

+ incompatible log format. Upstream has been informed of that. I am

+Description: Monitor for system resources and process activity
+ Atop is an ASCII full-screen performance monitor, similar to the top command,
+ but atop only shows the active system-resources and processes, and only shows
+ the deviations since the previous interval. At regular intervals, it shows
+ system-level activity related to the CPU, memory, swap, disks and network
+ layers, and it shows for every active process the CPU utilization in system
+ and user mode, the virtual and resident memory growth, priority, username,
+ state, and exit code. The process level activity is also shown for processes
+ which finished during the last interval, to get a complete overview about the
+ consumers of things such as CPU time.

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+ Take care that atopacctd terminates upon receipt of SIGTERM signal.
+ When activating a signal catcher via the signal() function, the SA_RESTART
+ flag is implicitly set. This means that a pending system call is
+ automatically restarted after the received signal is handled.
+ Instead, the sigaction system call is used now to activate a signal catcher
+ avoiding system calls to be restarted automatically.

+
+ Improved performance data gathering:
+ All process and thread related data is stored now
+ by function deviattask(), independent if the user
+ wants to view all data. In this way, immediate
+ reaction is garanteed for the 'a' key which allows
+ the user to view all processes/threads or to view
+ only the active processes/threads (previously,
+ the 'a' key was only effective after taking a new
+ sample).
+ Together with this modification, the behaviour of
+ the 'm' key (memory view) has changed by showing
+ automatically all processes instead of only the
+ active processes. After all, when viewing the memory
+ consumption of the processes, it is not relevant
+ whether or not that process has been active in the
+ last interval.

+ For the resident memory parts used by a process that are shared with
+ other processes, only a proportional part (shared memory part divided
+ by the number of sharers) is accounted to the process. Since the
+ gathering of this value is rather time-consuming (reading the
+ smaps file of every process), it is optional ('R' key or '-R' flag).

+
+ Improved handling of process accounting:
+ - Per sample not more than 50 MiB are allowed for process accounting records,
+ which means about 72000 processes. This avoids atop to explode in memory
+ when a huge amount of processes died within one sample.
+ - When only one atop-process is busy and it detects that the process accounting
+ file exceeds .5 GiB, it will truncate the accounting file to zero.

+INSTALLING AND USING ATOP
+
+For interactive use, it is sufficient to install ATOP with the command
+(as root):
+
+ make systemdinstall
+
+ or
+
+ make sysvinstall
+
+For automatic logging in compressed binary format, see the
+description in the manual-page.
+
+The kernel module 'netatop' can be downloaded and installed separately
+from www.atoptool.nl/downloadnetatop.php
+This module is optional and can be used to gather network statistics
+per process/thread as described in www.atoptool.nl/netatop.php
+
+
+KERNEL ISSUES WITH PROCESS ACCOUNTING
+-------------------------------------
+
+Newer upstream kernels (e.g. 4.8 and 4.9)have two issuess
+with process accounting:
+
+1) Sometimes process accounting does not work at all¹. Atopacctd tries to
+work around this issue, by retrying to initialize process accounting
+several times.
+
+2) When using the NETLINK inface, the command TASKSTATS_CMD_GET
+consequently returns -EINVAL². Atopacctd needs NETLINK to be able to
+be triggered that some process in the system has finished. In this way,
+atopacctd can be in a blocking state as long as no processes terminate.
+When atopacctd detects that NETLINK fails, it switches into a polling
+mode to periodically try if it can read process accounting records as
+a workaround. This issue has to do with cpumasks and you can work-around
+it by building a kernel that has CONFIG_NR_CPUS configured to exactly
+the amount of CPUs (logical CPUs) in the system the kernel runs on. You
+can find this kernel option under "Processor type and features" -->
+"Maximum number of CPUs".

+** ATOP - System & Process Monitor

+** - photosyst()
+** Takes a snapshot of the counters related to resource-usage on
+** system-level (cpu, disk, memory, network).
+** This code is UNIX-flavor dependent; in case of Linux the counters
+** are retrieved from /proc.
+**
+** - photoproc()
+** Takes a snapshot of the counters related to resource-usage of
+** tasks which are currently active. For this purpose the whole
+** task-list is read.
+** This code is UNIX-flavor dependent; in case of Linux the counters
+** are retrieved from /proc.
+**
+** - acctphotoproc()
+** Takes a snapshot of the counters related to resource-usage of
+** tasks which have been finished during the last interval.
+** For this purpose all new records in the accounting-file are read.
+**
+** When all counters have been gathered, functions are called to calculate
+** the difference between the current counter-values and the counter-values
+** of the previous cycle. These functions operate on the system-level
+** as well as on the task-level counters.
+** These differences are stored in a new structure(-table).
+**
+** - deviatsyst()
+** Calculates the differences between the current system-level
+** counters and the corresponding counters of the previous cycle.
+**
+** - deviattask()
+** Calculates the differences between the current task-level
+** counters and the corresponding counters of the previous cycle.
+** The per-task counters of the previous cycle are stored in the
+** task-database; this "database" is implemented as a linked list
+** of taskinfo structures in memory (so no disk-accesses needed).
+** Within this linked list hash-buckets are maintained for fast searches.
+** The entire task-database is handled via a set of well-defined
+** functions from which the name starts with "pdb_..." (see the
+** source-file procdbase.c).
+** The processes which have been finished during the last cycle
+** are also treated by deviattask() in order to calculate what their
+** resource-usage was before they finished.
+**
+** All information is ready to be visualized now.
+** There is a structure which holds the start-address of the
+** visualization-function to be called. Initially this structure contains
+** the address of the generic visualization-function ("generic_samp"), but
+** these addresses can be modified in the main-function depending on particular
+** flags. In this way various representation-layers (ASCII, graphical, ...)
+** can be linked with 'atop'; the one to use can eventually be chosen
+** at runtime.

+/*
+** The atopacctd daemon switches on the process accounting feature
+** in the kernel and let the process accounting records be written to
+** a file, called the source file. After process accounting is active,
+** the atopacctd daemon transfers every process accounting record that
+** is available in the source file to a shadow file.
+** Client processes (like atop) can read the shadow file instead of
+** the original process accounting source file.
+**
+** This approach has the following advantages:
+**
+** - The atopacctd daemon keeps the source file to a limited size
+** by truncating it regularly.
+**
+** - The atopacct daemon takes care that a shadow file has a limited size.
+** As soon as the current shadow file reaches its maximum size, the
+** atopacctd daemon creates a subsequent shadow file. For this reason,
+** the name of a shadow file contains a sequence number.
+** Shadow files that are not used by client processes any more, are
+** automatically removed by the atopacctd daemon.
+**
+** - When no client processes are active (any more), all shadow files
+** will be deleted and no records will be transferred to shadow files
+** any more. As soon as at least one client is activated again, the
+** atopacctd daemon start writing shadow files again.
+**
+** The directory /var/run is used as the default top-directory. An
+** alternative top-directory can be specified as command line argument
+** (in that case, also modify /etc/atoprc to inform atop as a client).
+** Below this top-directory the source file pacct_source is created and
+** the subdirectory pacct_shadow.d as a 'container' for the shadow files.

+.SH DESCRIPTION
+The program
+.I atop
+is an interactive monitor to view the load on a Linux system.
+It shows the occupation of the most critical hardware resources
+(from a performance point of view) on system level, i.e. cpu, memory, disk
+and network.
+.br
+It also shows which processes are responsible for the indicated
+load with respect to cpu and memory load on process level.
+Disk load is shown per process if "storage accounting" is active in the kernel.
+Network load is shown per process if the kernel module `netatop'
+has been installed.
+.PP
+Every
+.I interval
+(default: 10 seconds) information is shown about the resource occupation
+on system level (cpu, memory, disks and network layers), followed
+by a list of processes which have been active during the last interval
+(note that all processes that were unchanged during the last interval
+are not shown, unless the key 'a' has been pressed or unless sorting on
+memory occupation is done).
+If the list of active processes does not entirely fit on
+the screen, only the top of the list is shown (sorted in order of activity).
+.br
+The intervals are repeated till the number of
+.I samples
+(specified as command argument) is reached, or till the key 'q' is pressed
+in interactive mode.
+.PP
+When
+.I atop
+is started, it checks whether the standard output channel is connected to a
+screen, or to a file/pipe. In the first case it produces screen control
+codes (via the ncurses library) and behaves interactively; in the second case
+it produces flat ASCII-output.
+.PP
+In interactive mode, the output of
+.I atop
+scales dynamically to the current dimensions of the screen/window.
+.br
+If the window is resized horizontally, columns will be added or removed
+automatically. For this purpose, every column has a particular weight. The
+columns with the highest weights that fit within the current width will
+be shown.
+.br
+If the window is resized vertically, lines of the process/thread list
+will be added or removed automatically.
+.PP
+Furthermore in interactive mode the output of
+.I atop
+can be controlled by pressing particular keys.
+However it is also possible to specify such key as
+.B flag
+on the command line. In that case
+.I atop
+switches to the indicated mode on beforehand; this mode can
+be modified again interactively. Specifying such key as flag is especially
+useful when running
+.I atop
+with output to a pipe or file (non-interactively).
+These flags are the same as the keys that can be pressed in interactive
+mode (see section INTERACTIVE COMMANDS).
+.br
+Additional flags are available to support storage of atop-data in raw
+format (see section RAW DATA STORAGE).
+.SH PROCESS ACCOUNTING
+With every interval,
+.I atop
+reads the kernel administration to obtain information about all
+running processes.
+However, it is likely that during the interval also processes have terminated.
+These processes might have consumed system resources during
+this interval as well before they terminated.
+Therefor,
+.I atop
+tries to read the process accounting records that contain the accounting
+information of terminated processes and report these processes too.
+Only when the process accounting mechanism in the kernel is activated,
+the kernel writes such process accounting record to a file
+for every process that terminates.
+.PP
+There are various ways for
+.I atop
+to get access to the process accounting records (tried in this order):
+.PP
+.TP 4
+1.
+When the environment variable ATOPACCT is set,
+it specifies the name of the process accounting file.
+In that case, process accounting for this file
+should have been activated on beforehand.
+Before opening this file for reading,
+.I atop
+drops its root privileges (if any).
+.br
+When this environment variable is present but its
+contents is empty, process accounting will not be used at all.
+.PP
+.TP 4
+2.
+.B This is the preferred way of handling process accounting records!
+.br
+When the
+.I atopacctd
+daemon is active, it has activated the process accounting mechanism in
+the kernel and transfers to original accounting records to shadow files.
+In that case,
+.I atop
+drops its root privileges and opens the current shadow file for reading.
+.br
+This way is preferred, because the
+.I atopacctd
+daemon maintains full control of the sizes of the original process
+accounting file (written by the kernel) and the shadow files (read by the
+.I atop
+processes). For further information, refer to the
+.B atopacctd
+man page.
+.PP
+.TP 4
+3.
+When the
+.I atopacctd
+daemon is not active,
+.I atop
+verifies if the process accounting mechanism has been switched on
+via the separate
+.B psacct
+package. In that case, the file
+.B /var/account/pacct
+is in use as process accounting file and
+.I atop
+opens this file for reading.
+.PP
+.TP 4
+4.
+As a last possibility,
+.I atop
+itself tries to activate the process accounting mechanism (requires root
+privileges) using the file
+.B /var/cache/atop.d/atop.acct
+(to be written by the kernel, to be read by
+.I atop
+itself). Process accounting remains active as long as
+at least one
+.I atop
+process is alive.
+Whenever the last
+.I atop
+process stops (either by pressing `q' or by `kill \-15'), it deactivates the
+process accounting mechanism again. Therefor you should never terminate
+.I atop
+by `kill \-9', because then it has no chance to stop process accounting.
+As a result, the accounting file may consume a lot of
+disk space after a while.
+.br
+To avoid that the process accounting file consumes too much disk space,
+.I atop
+verifies at the end of every sample if the size of the process accounting
+file exceeds 200 MiB and if this
+.I atop
+process is the only one that is currently using the file.
+In that case the file is truncated to a size of zero.
+
+Notice that root-privileges are required to switch on/off process accounting
+in the kernel. You can start
+.I atop
+as a root user or specify setuid-root privileges to the executable file.
+In the latter case,
+.I atop
+switches on process accounting and drops the root-privileges again.
+.br
+If
+.I atop
+does not run with root-privileges, it does not show information
+about finished processes.
+It indicates this situation with the message
+message `no procacct` in the top-right corner (instead of the counter that
+shows the number of exited processes).
+.PP
+When during one interval a lot of processes have finished,
+.I atop
+might grow tremendously in memory when reading all process accounting
+records at the end of the interval. To avoid such excessive growth,
+.I atop
+will never read more than 50 MiB with process information from the
+process accounting file per interval (approx. 70000 finished processes).
+In interactive mode a warning is given whenever processes have been skipped
+for this reason.
+.PP
+.SH COLORS
+For the resource consumption on system level,
+.I atop
+uses colors to indicate that a critical occupation percentage has
+been (almost) reached.
+A critical occupation percentage means that is likely that this load
+causes a noticeable negative performance influence for applications using
+this resource. The critical percentage depends on the type of resource:
+e.g. the performance influence of a disk with a busy percentage of 80%
+might be more noticeable for applications/user than a CPU with a busy
+percentage of 90%.
+.br
+Currently
+.I atop
+uses the following default values to calculate a weighted percentage
+per resource:
+.PP
+.TP 5
+.B \ Processor
+A busy percentage of 90% or higher is considered `critical'.
+.TP 5
+.B \ Disk
+A busy percentage of 70% or higher is considered `critical'.
+.TP 5
+.B \ Network
+A busy percentage of 90% or higher for the load of an interface is
+considered `critical'.
+.TP 5
+.B \ Memory
+An occupation percentage of 90% is considered `critical'.
+Notice that this occupation percentage is the accumulated memory
+consumption of the kernel (including slab) and all processes; the
+memory for the page cache (`cache' and `buff' in the MEM-line) and the
+reclaimable part of the slab (`slrec`) is not implied!
+.br
+If the number of pages swapped out (`swout' in the PAG-line) is larger
+than 10 per second, the memory resource is considered `critical'.
+A value of at least 1 per second is considered `almost critical'.
+.br
+If the committed virtual memory exceeds the limit (`vmcom' and `vmlim'
+in the SWP-line), the SWP-line is colored due to overcommitting the system.
+.TP 5
+.B \ Swap
+An occupation percentage of 80% is considered `critical'
+because swap space might be completely exhausted in the near future;
+it is not critical from a performance point-of-view.
+.PP
+These default values can be modified in the configuration file
+(see separate man-page of atoprc).
+.PP
+When a resource exceeds its critical occupation percentage, the concerning
+values in the screen line are colored red by default.
+.br
+When a resource exceeded (default) 80% of its critical percentage
+(so it is almost critical), the concerning values in the screen line
+are colored cyan by default. This `almost critical percentage' (one value
+for all resources) can be modified in the configuration file
+(see separate man-page of atoprc).
+.br
+The default colors red and cyan can be modified in the configuration file
+as well (see separate man-page of atoprc).
+.PP
+With the key 'x' (or flag \-x), the use of colors can be suppressed.
+.SH NETATOP MODULE
+Per-process and per-thread network activity can be measured by the
+.I netatop
+kernel module. You can download this kernel module from the website
+(mentioned at the end of this manual page) and install it on your
+system if the kernel version is 2.6.24 or newer.
+.br
+When
+.I atop
+gathers counters for a new interval, it verifies if the
+.I netatop
+module is currently active. If so,
+.I atop
+obtains the relevant network counters from this module and shows
+the number of sent and received packets per process/thread in the generic
+screen. Besides, detailed counters can be requested by
+pressing the `n' key.
+.br
+When the
+.I netatopd
+daemon is running as well,
+.I atop
+also reads the network counters of exited processes that are logged
+by this daemon (comparable with process accounting).
+.PP
+More information about the optional
+.I netatop
+kernel module and the
+.I netatopd
+daemon can be found in the concerning man-pages and on the website
+mentioned at the end of this manual page.
+.SH INTERACTIVE COMMANDS
+When running
+.I atop
+interactively (no output redirection), keys can be pressed to control the
+output. In general, lower case keys can be used to show other information for
+the active processes and upper case keys can be used to influence the
+sort order of the active process/thread list.
+.PP
+.TP 5
+.B g

+.SH RAW DATA STORAGE
+In order to store system and process level statistics for long-term
+analysis (e.g. to check the system load and the active processes running
+yesterday between 3:00 and 4:00 PM),
+.I atop
+can store the system and process level statistics in
+compressed binary format in a raw file with the flag
+.B -w
+followed by the filename.
+If this file already exists and is recognized as a raw data file,
+.I atop
+will append new samples to the file (starting with a sample which reflects
+the activity since boot); if the file does not exist, it will be created.
+.br
+All processes/threads are stored in the raw file.
+.br
+The interval (default: 10 seconds) and number of samples (default: infinite)
+can be passed as last arguments. Instead of the number of samples, the flag
+.B -S
+can be used to indicate that
+.I atop
+should finish anyhow before midnight.
+.PP
+A raw file can be read and visualized again with the flag
+.B -r
+followed by the filename. If no filename is specified, the file
+.BI /var/log/atop/atop_ YYYYMMDD
+is opened for input (where
+.I YYYYMMDD
+are digits representing the current date).
+If a filename is specified in the format YYYYMMDD (representing any valid
+date), the file
+.BI /var/log/atop/atop_ YYYYMMDD
+is opened.
+If a filename with the symbolic name
+.BI y
+is specified, yesterday's daily logfile is opened
+(this can be repeated so 'yyyy' indicates the logfile of four days ago).
+.br
+The samples from the file can be viewed interactively by using the key 't'
+to show the next sample, the key 'T' to show the previous sample, the
+key 'b' to branch to a particular time or the key 'r' to rewind to
+the begin of the file.
+.br
+When output is redirected to a file or pipe,
+.B atop
+prints all samples in plain ASCII. The default line length is 80 characters
+in that case; with the flag
+.B -L
+followed by an alternate line length, more (or less) columns will be shown.
+.br
+With the flag
+.B -b
+(begin time) and/or
+.B -e
+(end time) followed by a time argument of the form HH:MM,
+a certain time period within the raw file can be selected.
+.PP
+When

+is installed, the script
+.B atop.daily
+is stored in the

+is restarted again after the rotation.
+When the package
+.B psacct
+is not installed, these logrotate-files have no effect.
+.SH OUTPUT DESCRIPTION
+The first sample shows the system level activity since boot
+(the elapsed time in the header shows the time since boot).
+Note that particular counters could have reached their maximum
+value (several times) and started by zero again,
+so do not rely on these figures.
+.PP
+For every sample
+.I atop
+first shows the lines related to system level activity. If a particular
+system resource has not been used during the interval, the entire line
+related to this resource is suppressed. So the number of system level lines
+may vary for each sample.
+.br
+After that a list is shown of processes which have been active during the last
+interval. This list is by default sorted on cpu consumption, but this order
+can be changed by the keys which are previously described.
+.PP
+If values have to be shown by
+.I atop
+which do not fit in the column width,
+another format is used. If e.g. a cpu-consumption of 233216 milliseconds
+should be shown in a column width of 4 positions, it is shown as `233s'
+(in seconds).
+For large memory figures, another unit is chosen if the value does not fit
+(Mb instead of Kb, Gb instead of Mb, Tb instead of Gb, ...).
+For other values, a kind of exponent notation is used (value 123456789
+shown in a column of 5 positions gives 123e6).
+.SH OUTPUT DESCRIPTION - SYSTEM LEVEL
+The system level information consists of the following output lines:
+.PP
+.TP 5
+.B PRC
+Process and thread level totals.
+.br
+This line contains the total cpu time consumed
+in system mode (`sys') and in user mode (`user'),
+the total number of processes present at this moment (`#proc'),
+the total number of threads present at this moment in state `running' (`#trun'),
+`sleeping interruptible' (`#tslpi') and `sleeping uninterruptible' (`#tslpu'),
+the number of zombie processes (`#zombie'),
+the number of clone system calls (`clones'), and
+the number of processes that ended during the interval
+(`#exit') when process accounting is used. Instead of `#exit` the last
+column may indicate that process accounting could not be activated
+(`no procacct`).
+.br
+If the screen-width does not allow all of these counters,
+only a relevant subset is shown.
+.PP
+.TP 5
+.B CPU
+CPU utilization.
+.br
+At least one line is shown for the total occupation of all CPUs together.
+.br
+In case of a multi-processor system, an additional line is shown
+for every individual processor (with `cpu' in lower case),
+sorted on activity. Inactive CPUs will not be shown by default.
+The lines showing the per-cpu occupation contain the cpu number in
+the last field.
+
+Every line contains the percentage of cpu time spent in
+kernel mode by all active processes (`sys'),
+the percentage of cpu time consumed in user mode (`user') for all
+active processes (including processes running with a nice value larger than
+zero), the percentage of cpu time spent for interrupt handling (`irq')
+including softirq, the percentage of unused cpu time while no processes
+were waiting for disk-I/O (`idle'), and
+the percentage of unused cpu time while at least one process was waiting
+for disk-I/O (`wait').
+.br
+In case of per-cpu occupation, the last column shows the cpu number and
+the wait percentage (`w') for that cpu.
+The number of lines showing the per-cpu occupation can be limited.
+
+For virtual machines the steal-percentage is shown (`steal'), reflecting
+the percentage of cpu time stolen by other virtual machines
+running on the same hardware.
+.br
+For physical machines hosting one or more virtual machines,
+the guest-percentage is shown (`guest'), reflecting
+the percentage of cpu time used by the virtual machines. Notice that
+this percentage overlaps the user-percentage.
+
+In case of frequency-scaling, all previously mentioned CPU-percentages
+are relative to the used scaling of the CPU during the interval.
+If a CPU has been active for e.g. 50% in user mode during the interval
+while the frequency-scaling of that CPU was 40%, only 20% of the full
+capacity of the CPU has been used in user mode.
+.br
+In case that the kernel module `cpufreq_stats' is active
+(after issueing `modprobe cpufreq_stats'), the
+.I average
+frequency (`avgf') and the
+.I average
+scaling percentage (`avgscal') is shown. Otherwise the
+.I current
+frequency (`curf') and the
+.I current
+scaling percentage (`curscal') is shown at the moment that the sample
+is taken.
+
+If the screen-width does not allow all of these counters,
+only a relevant subset is shown.
+.PP
+.TP 5
+.B CPL
+CPU load information.
+.br
+This line contains the load average figures reflecting the number
+of threads that are available to run on a CPU (i.e. part of the runqueue)
+or that are waiting for disk I/O. These figures are averaged over
+1 (`avg1'), 5 (`avg5') and 15 (`avg15') minutes.
+.br
+Furthermore the number of context switches (`csw'), the number
+of serviced interrupts (`intr') and the number of available CPUs are shown.
+
+If the screen-width does not allow all of these counters,
+only a relevant subset is shown.
+.PP
+.TP 5
+.B MEM
+Memory occupation.
+.br
+This line contains the total amount of physical memory
+(`tot'), the amount of memory which is currently free (`free'),
+the amount of memory in use as page cache including
+the total resident shared memory (`cache'), the amount of memory within the
+page cache that has to be flushed to disk (`dirty'), the amount
+of memory used for filesystem meta data (`buff'), the amount of
+memory being used for kernel mallocs (`slab'), the amount of
+slab memory that is reclaimable (`slrec'), the resident size of shared
+memory including tmpfs (`shmem`), the resident size of shared memory (`shrss`)
+the amount of shared memory that is currently swapped (`shswp`),
+the amount of memory that is currently claimed by vmware's
+balloon driver (`vmbal`),
+the amount of memory that is claimed for huge pages (`hptot`),
+and the amount of huge page memory that is really in use (`hpuse`).
+
+If the screen-width does not allow all of these counters,
+only a relevant subset is shown.
+.PP
+.TP 5
+.B SWP
+Swap occupation and overcommit info.
+.br
+This line contains the total amount of swap space on disk (`tot') and
+the amount of free swap space (`free').
+.br
+Furthermore the committed virtual memory space (`vmcom') and the maximum
+limit of the committed space (`vmlim', which is by default swap size
+plus 50% of memory size) is shown.
+The committed space is the reserved virtual space for all allocations of
+private memory space for processes. The kernel only verifies whether the
+committed space exceeds the limit if strict overcommit handling is
+configured (vm.overcommit_memory is 2).
+.PP
+.TP 5
+.B PAG
+Paging frequency.
+.br
+This line contains the number of scanned pages (`scan') due to the fact
+that free memory drops below a particular threshold and the number
+times that the kernel tries to reclaim pages due to an urgent need (`stall').
+.br
+Also the number of memory pages the system read from swap space (`swin')
+and the number of memory pages the system wrote to swap space (`swout')
+are shown.
+.PP
+.TP 5
+.B LVM/MDD/DSK
+Logical volume/multiple device/disk utilization.
+.br
+Per active unit one line is produced, sorted on unit activity.
+Such line shows the name (e.g. VolGroup00-lvtmp for a logical volume or
+sda for a hard disk), the busy percentage i.e. the portion of time that the
+unit was busy handling requests (`busy'), the number of read requests issued
+(`read'), the number of write requests issued (`write'),
+the number of KiBytes per read (`KiB/r'),
+the number of KiBytes per write (`KiB/w'),
+the number of MiBytes per second throughput for reads (`MBr/s'),
+the number of MiBytes per second throughput for writes (`MBw/s'),
+the average queue depth (`avq')
+and the average number of milliseconds needed by a request (`avio')
+for seek, latency and data transfer.
+.br
+If the screen-width does not allow all of these counters,
+only a relevant subset is shown.
+
+The number of lines showing the units can be limited per class (LVM, MDD or
+DSK) with the 'l' key or statically (see separate man-page of atoprc).
+By specifying the value 0 for a particular class, no lines will be
+shown any more for that class.
+.PP
+.TP 5
+.B NFM
+Network Filesystem (NFS) mount at the client side.
+.br
+For each NFS-mounted filesystem, a line is shown that contains
+the mounted server directory, the name of the server (`srv'),
+the total number of bytes physically read from the server (`read') and
+the total number of bytes physically written to the server (`write').
+Data transfer is subdivided in
+the number of bytes read via normal read() system calls (`nread'),
+the number of bytes written via normal read() system calls (`nwrit'),
+the number of bytes read via direct I/O (`dread'),
+the number of bytes written via direct I/O (`dwrit'),
+the number of bytes read via memory mapped I/O pages (`mread'), and
+the number of bytes written via memory mapped I/O pages (`mwrit').
+.PP
+.TP 5
+.B NFC
+Network Filesystem (NFS) client side counters.
+.br
+This line contains the number of RPC calls issues by local processes
+(`rpc'), the number of read RPC calls (`read`) and
+write RPC calls (`rpwrite') issued to the NFS server,
+the number of RPC calls being retransmitted (`retxmit')
+and the number of authorization refreshes (`autref').
+.PP
+.TP 5
+.B NFS
+Network Filesystem (NFS) server side counters.
+.br
+This line contains the number of RPC calls received from
+NFS clients (`rpc'),
+the number of read RPC calls received (`cread`),
+the number of write RPC calls received (`cwrit'),
+the number of network requests handled via TCP (`nettcp'),
+the number of network requests handled via UDP (`netudp'),

+the number of Megabytes/second passed in write requests by clients (`MBcw/s`),
+the number of reply cache hits (`rchits'),
+the number of reply cache misses (`rcmiss') and
+the number of uncached requests (`rcnoca').
+Furthermore some error counters indicating the number of requests
+with a bad format (`badfmt') or a bad authorization (`badaut'), and a
+counter indicating the number of bad clients (`badcln').
+and the number of authorization refreshes (`autref').
+.PP
+.TP 5
+.B NET
+Network utilization (TCP/IP).
+.br
+One line is shown for activity of the transport layer (TCP and UDP), one line
+for the IP layer and one line per active interface.
+.br
+For the transport layer,
+counters are shown concerning the number of received TCP segments
+including those received in error (`tcpi'),
+the number of transmitted TCP segments excluding
+those containing only retransmitted octets (`tcpo'),
+the number of UDP datagrams received (`udpi'),
+the number of UDP datagrams transmitted (`udpo'),

+the number of UDP no ports (`udpnp'), and
+the number of UDP input errors (`udpie').
+.br
+If the screen-width does not allow all of these counters,
+only a relevant subset is shown.
+.br
+These counters are related to IPv4 and IPv6 combined.
+
+For the IP layer, counters are shown concerning the number of IP datagrams

+Such line shows the name of the interface and its busy percentage
+in the first column.
+The busy percentage for half duplex is determined by comparing the
+interface speed with the number of bits transmitted and received
+per second; for full duplex the interface speed is compared with the
+highest of either the transmitted or the received bits.

+only a relevant subset is shown.
+.br
+The number of lines showing the network interfaces can be limited.
+.SH OUTPUT DESCRIPTION - PROCESS LEVEL
+Following the system level information, the processes are shown from which the
+resource utilization has changed during the last interval. These processes
+might have used cpu time or issued disk or network requests. However a process
+is also shown if part of it has been paged out due to lack of memory (while
+the process itself was in sleep state).
+.PP
+Per process the following fields may be shown (in alphabetical order),
+depending on the current output mode as described in the section
+INTERACTIVE COMMANDS and depending on the current width of your window:
+.PP
+.TP 9
+.B AVGRSZ
+The average size of one read-action on disk.
+.PP
+.TP 9
+.B AVGWSZ
+The average size of one write-action on disk.
+.PP

+.B BANDWI
+Total bandwidth for received TCP and UDP packets consumed by this process
+(bits-per-second).
+This value can be compared with the value `si'
+on interface level (used bandwidth per interface).
+.br
+This information will only be shown when the kernel module `netatop'
+is loaded.
+.PP

+.B BANDWO
+Total bandwidth for sent TCP and UDP packets consumed by this process
+(bits-per-second).
+This value can be compared with the value `so'

+.br
+This information will only be shown when the kernel module `netatop'
+is loaded.
+.PP
+.TP 9
+.B CID
+Container ID (Docker) of 12 hexadecimal digits, referring to the container
+in which the process/thread is running.
+If a process has been started and finished during the last
+interval, a `?' is shown because the container ID is not part of
+the standard process accounting record.
+.PP
+.TP 9
+.B CMD
+The name of the process.
+This name can be surrounded by "less/greater than"
+signs (`<name>') which means that the process has finished during the last
+interval.
+.br
+Behind the abbreviation `CMD' in the header line, the current page number and
+the total number of pages of the process/thread list are shown.
+.PP
+.TP 9
+.B COMMAND-LINE
+The full command line of the process (including arguments). If the length of
+the command line exceeds the length of the screen line, the arrow
+keys -> and <- can be used for horizontal scroll.
+.br
+Behind the verb `COMMAND-LINE' in the header line, the current page number
+and the total number of pages of the process/thread list are shown.

+.TP 9
+.B CPUNR
+The identification of the CPU the (main) thread is running on
+or has recently been running on.
+.PP
+.TP 9
+.B CTID
+Container ID (OpenVZ).

+the standard process accounting record.
+.PP
+.TP 9
+.B DSK
+The occupation percentage of this process related to the total load that
+is produced by all processes (i.e. total disk accesses
+by all processes during the last interval).
+.br
+This information is shown when per process "storage accounting" is active
+in the kernel.
+.PP
+.TP 9
+.B EGID
+Effective group-id under which this process executes.
+.PP
+.TP 9
+.B ENDATE
+Date that the process has been finished. If the process is still running,
+this field shows `active'.
+.PP
+.TP 9
+.B ENTIME
+Time that the process has been finished. If the process is still running,
+this field shows `active'.
+.PP
+.TP 9

+.PP
+.TP 9

+.PP
+.TP 9
+.B NET
+The occupation percentage of this process related to the total load that
+is produced by all processes (i.e. consumed network bandwidth
+of all processes during the last interval).
+.br
+This information will only be shown when kernel module `netatop' is loaded.
+.PP
+.TP 9
+.B NICE
+The more or less static priority that can be given to a process on a
+scale from -20 (high priority) to +19 (low priority).
+.PP
+.TP 9
+.B NPROCS
+The number of active and terminated processes accumulated for this user
+or program.
+.PP
+.TP 9
+.B PID
+Process-id.
+If a process has been started and finished during the last
+interval, a `?' is shown because the process-id is not part of
+the standard process accounting record.
+.PP
+.TP 9
+.B POLI
+The policies 'norm' (normal, which is SCHED_OTHER), 'btch' (batch)
+and 'idle' refer to timesharing processes.
+The policies 'fifo' (SCHED_FIFO) and 'rr' (round robin, which is SCHED_RR)
+refer to realtime processes.
+.PP
+.TP 9
+.B PPID
+Parent process-id.
+If a process has been started and finished during the last
+interval, value 0 is shown because the parent process-id is not part of
+the standard process accounting record.
+.PP
+.TP 9
+.B PRI
+The process' priority ranges from 0 (highest priority) to 139 (lowest
+priority). Priority 0 to 99 are used for realtime processes (fixed
+priority independent of their behavior) and priority 100 to 139 for
+timesharing processes (variable priority depending on their recent
+CPU consumption and the nice value).
+.PP
+.TP 9
+.B PSIZE
+The proportional memory size of this process (or user).
+.br
+Every process shares resident memory with other processes. E.g. when a
+particular program is started several times, the code pages (text) are
+only loaded once in memory and shared by all incarnations. Also the code
+of shared libraries is shared by all processes using that shared library,
+as well as shared memory and memory-mapped files.
+For the PSIZE calculation of a process, the resident memory of a process
+that is shared with other processes is divided by the number of sharers.
+This means, that every process is accounted for a proportional part of
+that memory. Accumulating the PSIZE values of all processes in the
+system gives a reliable impression of the total resident memory consumed
+by all processes.
+.br
+Since gathering of all values that are needed to calculate the PSIZE is a
+relatively time-consuming task, the 'R' key (or '-R' flag) should
+be active. Gathering these values also requires superuser privileges
+(otherwise '?K' is shown in the output).
+.br
+If a process has finished during the last interval, no value is shown
+since the proportional memory size is not part of the standard
+process accounting record.
+.PP
+.TP 9
+.B RDDSK
+When the kernel maintains standard io statistics (>= 2.6.20):
+.br
+The read data transfer issued physically on disk (so reading from the
+disk cache is not accounted for).
+.br
+Unfortunately, the kernel aggregates the
+data tranfer of a process to the data transfer of its parent process when
+terminating, so you might see transfers for (parent) processes like
+cron, bash or init, that are not really issued by them.
+.PP
+.TP 9
+.B RGID
+The real group-id under which the process executes.
+.PP
+.TP 9
+.B RGROW
+The amount of resident memory that the process has grown during the last
+interval. A resident growth can be caused by touching memory pages which
+were not physically created/loaded before (load-on-demand).
+Note that a resident growth can also be negative e.g. when part of the process
+is paged out due to lack of memory or when the process frees dynamically
+allocated memory.
+For a process which started during the last interval, the resident growth
+reflects the total resident size of the process at that moment.
+.br
+If a process has finished during the last interval, no value is shown
+since resident memory occupation is not part of the standard
+process accounting record.
+.PP
+.TP 9
+.B RNET
+The number of TCP- and UDP packets received by this process.
+This information will only be shown when kernel module `netatop' is installed.
+.br
+If a process has finished during the last interval, no value is shown
+since network counters are not part of the standard process accounting record.
+.PP
+.TP 9
+.B RSIZE
+The total resident memory usage consumed by this process (or user).
+Notice that the RSIZE of a process includes all resident memory used
+by that process, even if certain memory parts are shared with other processes
+(see also the explanation of PSIZE).
+.br
+If a process has finished during the last interval, no value is shown
+since resident memory occupation is not part of the standard
+process accounting record.
+.PP
+.TP 9
+.B RTPR
+Realtime priority according the POSIX standard.
+Value can be 0 for a timesharing process (policy 'norm', 'btch' or 'idle')
+or ranges from 1 (lowest) till 99 (highest) for a realtime process
+(policy 'rr' or 'fifo').
+.PP
+.TP 9
+.B RUID
+The real user-id under which the process executes.
+.PP
+.TP 9
+.B S
+The current state of the (main) thread: `R' for running
+(currently processing or in the runqueue), `S' for sleeping interruptible
+(wait for an event to occur),
+`D' for sleeping non-interruptible, `Z' for zombie (waiting to be synchronized
+with its parent process), `T' for stopped (suspended or traced), `W' for
+swapping, and `E' (exit) for processes which have finished during the last
+interval.
+.PP
+.TP 9
+.B SGID
+The saved group-id of the process.
+.PP
+.TP 9
+.B SNET
+The number of TCP and UDP packets transmitted by this process.
+This information will only be shown when the kernel module `netatop'

+.PP
+.TP 9
+.B ST
+The status of a process.
+.br
+The first position indicates if the process has been
+started during the last interval (the value
+.I N
+means 'new process').
+
+The second position indicates if the process has been
+finished during the last interval.
+.br
+The value
+.I E
+means 'exit' on the process' own initiative; the exit code is displayed
+in the column `EXC'.
+.br
+The value
+.I S
+means that the process has been terminated unvoluntarily
+by a signal; the signal number is displayed in the in the column `EXC'.
+.br
+The value
+.I C
+means that the process has been terminated unvoluntarily
+by a signal, producing a core dump in its current directory;
+the signal number is displayed in the column `EXC'.
+.PP
+.TP 9
+.B STDATE
+The start date of the process.
+.PP
+.TP 9

+The start time of the process.
+.PP
+.TP 9
+.B SUID

+.B SYSCPU
+CPU time consumption of this process in system mode (kernel mode), usually
+due to system call handling.

+.B THR
+Total number of threads within this process.
+All related threads are contained in a thread group, represented by
+.I atop
+as one line or as a separate line when the 'y' key (or -y flag) is active.
+
+On Linux 2.4 systems it is hardly possible to determine
+which threads (i.e. processes) are related to the same thread group.
+Every thread is represented by
+.I atop
+as a separate line.
+.PP
+.TP 9
+.B TID
+Thread-id.
+All threads within a process run with the same PID but with a
+different TID. This value is shown for individual threads in

+(including heap and shared library data).
+.PP
+.TP 9
+.B VGROW
+The amount of virtual memory that the process has grown during the last
+interval. A virtual growth can be caused by e.g. issueing a malloc()
+or attaching a shared memory segment. Note that a virtual growth can also
+be negative by e.g. issueing a free() or detaching a shared memory segment.
+For a process which started during the last interval, the virtual growth
+reflects the total virtual size of the process at that moment.
+.br
+If a process has finished during the last interval, no value is shown
+since virtual memory occupation is not part of the standard
+process accounting record.
+.PP
+.TP 9
+.B VPID
+Virtual process-id (within an OpenVZ container).
+If a process has been started and finished during the last
+interval, a `?' is shown because the virtual process-id is not part of
+the standard process accounting record.
+.PP
+.TP 9
+.B VSIZE
+The total virtual memory usage consumed by this process (or user).
+.br
+If a process has finished during the last interval, no value is shown
+since virtual memory occupation is not part of the standard
+process accounting record.
+.PP
+.TP 9
+.B VSLIBS
+The virtual memory size of the (shared) text of all shared libraries used
+by this process.
+.PP
+.TP 9
+.B VSTACK
+The virtual memory size of the (private) stack used by this process
+.PP
+.TP 9
+.B VSTEXT
+The virtual memory size of the (shared) text of the executable program.
+.PP
+.TP 9
+.B WRDSK
+When the kernel maintains standard io statistics (>= 2.6.20):
+.br
+The write data transfer issued physically on disk (so writing to the
+disk cache is not accounted for).
+This counter is maintained for the application process that writes its
+data to the cache (assuming that this data is physically transferred
+to disk later on). Notice that disk I/O needed for swapping is
+not taken into account.
+.br
+Unfortunately, the kernel aggregates the
+data tranfer of a process to the data transfer of its parent process when
+terminating, so you might see transfers for (parent) processes like
+cron, bash or init, that are not really issued by them.
+.PP
+.TP 9
+.B WCANCL
+When the kernel maintains standard io statistics (>= 2.6.20):
+.br
+The write data transfer previously accounted for this process
+or another process that has been cancelled.
+Suppose that a process writes new data to a file and that data is removed
+again before the cache buffers have been flushed to disk.
+Then the original process shows the written data as WRDSK, while
+the process that removes/truncates the file shows
+the unflushed removed data as WCANCL.

+.SH NAME
+.B atopacctd
+- process accounting daemon
+.SH SYNOPSIS
+.P
+.B atopacctd
+[-v | topdirectory]
+.P
+.SH DESCRIPTION
+The
+.I atopacctd
+daemon switches on the process accounting feature in the kernel
+and let the process accounting records be written to a file,
+called the source file from now.
+After process accounting is activated, the
+.I atopacctd
+daemon transfers every process accounting record that is available
+in the source file to a shadow file.
+Client processes (like
+.I atop
+processes) will read the shadow files instead of the
+process accounting source file.
+.br
+In this way, the
+.I atopacctd
+daemon operates as a 'layer' between the process accounting file
+that is written by the kernel and the shadow accounting files that are read by
+.I atop
+processes.
+.PP
+This approach has the following advantages:
+.PP
+.TP 3
+.B o
+The
+.I atopacctd
+daemon takes care that the source file is kept to a limited size.
+As soon as its maximum size is reached, it is truncated to a size
+of zero again (this is not noticed by the
+.I atop
+processes).
+.PP
+.TP 3
+.B o
+The
+.I atopacct
+daemon takes care that a shadow file is kept to a limited size.
+As soon as the current shadow file reaches this maximum size, the
+.I atopacctd
+daemon creates a new (subsequent) shadow file.
+While client processes still have the possibility to read the previous
+shadow file(s), the
+.I atopacctd
+daemon continues writing accounting records to the newest (current)
+shadow file.
+For this reason, the name of a shadow file consists of a 10-digit
+sequence number followed by the extension '.paf' (process acounting file).
+Old shadow files that are not used by client processes any more, are
+automatically removed by the garbage collector in the
+.I atopacctd
+daemon.
+.PP
+.TP 3
+.B o
+When no client processes are active (any more), all shadow files
+will be deleted and no records will be transferred to a shadow file
+any more. As soon as at least one client is activate again, the
+.I atopacctd
+daemon continues writing shadow files.
+.PP
+The directory
+.B /var/run
+is used as the default topdirectory.
+Below this top-directory, the source file
+.B pacct_source
+is created to which the kernel writes the process accounting records.
+.br
+Furthermore, the subdirectory
+.B pacct_shadow.d
+is created as a 'container' for the shadow files.
+Apart from the shadow files, also the file
+.B current
+is maintained in this subdirectory, containing the sequence number of the
+current (newest) shadow file and the maximum number of records that will be
+written in each shadow file.
+.PP
+An alternative topdirectory can be specified as command line argument.
+When an alternative topdirectory is defined, also modify the
+configuration file
+.B /etc/atoprc
+to inform
+.I atop
+clients about this alternative location (see the
+.B atoprc
+man page).
+Such alternative topdirectory should be owned by root and may not be
+writable for the group or others (security reasons).
+.PP
+Notice that the kernel suspends writing process accounting records
+when the free space of the filesystem on which the process accounting file
+resides drops below 2%. Writing is resumed when the free space is 4% or more.
+These lowwater and highwater percentages can be configured via the
+.B /proc/sys/kernel/acct
+pseudo-file.
+.br
+The
+.I atopacctd
+daemon suspends transferring process accounting records to shadow files
+when the free space of the filesystem on which the process accounting file
+resides drops below 5%. Transfer is resumed when the free space is 5% or more.
+Log messages are generated via syslog when writing to the current shadow
+file is suspended or resumed.
+.PP
+The
+.B -v
+flag can be used to verify the version of the
+.I atopacctd
+daemon.
+.PP
+.SH FILES
+.PP
+.TP 5
+.B /var/run/pacct_source
+Regular file to which the kernel writes the process accounting records.
+This file will be regularly truncated.

+The keywords 'ownprocline' and 'ownpagline' are explained in the
+subsequent section.
+.SH OWN DEFINITION OF OUTPUT LINE
+Via the rcfile it is possible to define the layout of the output lines
+yourself, i.e. you can define the layout of one line with process information
+with the keyword 'ownprocline' (to be selected with the key 'o'
+or the flag \-o) and you can redefine all lines with system information.
+.PP
+The layout of an output-line can be defined as follows
+(notice that this should be specified as one line in the rcfile):
+.PP
+\ \ \ keyword\ \ \ <columnid>:<prio> [<columnid>:<prio> ...]
+.PP
+The
+.B columnid
+is the symbolic name of a column that should shown at this position
+in the output line.
+.br
+The
+.B prio
+is a positive integer value that determines which columns have precedence
+whenever not all specified columns fit into the current screen-width.
+The higher value, the higher priority.
+.br
+The column-specifications should be separated by a space. The order
+in which columns have been specified is the order in which they will be
+shown, with respect to their priority (columns that do not fit, will be
+dropped dynamically).
+.PP
+A special columnid for system lines is 'BLANKBOX'. This indicates
+that an empty column is required at this position. Also this
+special columnid is followed by a priority (usually low).
+.PP
+The following definition can be specified for process information:
+.PP
+.TP 4
+.B ownprocline
+The columnid's are the names of the columns that are shown in the
+normal output of the process-related lines that are shown by
+.I atop
+such as 'PID', 'CMD', 'S', ....
+The only exception is the special columnid 'SORTITEM' that is used to
+show one of the columns CPU%/DSK%/MEM%/NET%, depending on the chosen
+sort-criterium.

+.P
+.SH DESCRIPTION
+The program
+.I atopsar
+can be used to report statistics on system level.
+.PP
+In the first synopsis line (no sampling interval specified),
+.I atopsar
+extracts data from a raw logfile that has been recorded previously by
+the program
+.I atop
+(option
+.B -w
+of the
+.I atop
+program).
+.br
+You can specify the name of the logfile with the
+.B -r
+option of the
+.I atopsar
+program.
+When a daily logfile of
+.I atop
+is used, named
+.B /var/log/atop/atop_YYYYMMDD
+(where YYYYMMDD reflects the date),
+the required date of the form YYYYMMDD can be specified with the
+.B -r
+option instead of the filename, or
+the symbolic name 'y' can be used for yesterday's daily logfile
+(this can be repeated so 'yyyy' indicates the logfile of four days ago).
+If the
+.B -r
+option is not specified at all, today's daily logfile is used by default.
+.br
+The starting and ending times of the report can be defined using the
+options
+.B -b
+and
+.B -e
+followed by a time argument of the form hh:mm.
+.PP
+In the second synopsis line,
+.B atopsar
+reads actual activity counters from the kernel with the specified
+.I interval
+(in seconds) and the specified number of
+.I samples
+(optionally).
+When
+.B atopsar
+is activated in this way it immediately sends the output for every requested
+report to standard output.
+If only one type of report is requested, the header is printed
+once and after every
+.I interval
+seconds the statistical counters are shown for that period.
+If several reports are requested, a header is printed per sample
+followed by the statistical counters for that period.
+.PP
+Some generic flags can be specified to influence the behaviour of the
+.B atopsar
+program:
+.PP
+.TP 5
+.B -S
+By default the timestamp at the beginning of a line is suppressed if more
+lines are shown for one interval. With this flag a timestamp is
+given for every output-line (easier for post-processing).
+.PP
+.TP 5
+.B -a
+By default certain resources as disks and network interfaces are only
+shown when they were active during the interval.
+With this flag all resources of a given type are shown, even if
+they were inactive during the interval.
+.PP
+.TP 5
+.B -x
+By default
+.B atopsar
+only uses colors if output is directed to a terminal (window).
+These colors might indicate that a critical occupation percentage has
+been reached (red) or has been almost reached (cyan) for a particular
+resource.
+See the man-page of
+.B atop
+for a detailed description of this feature (section COLORS).
+.br
+With the flag
+.B -x
+the use of colors is suppressed unconditionally.
+.PP
+.TP 5
+.B -C
+By default
+.B atopsar
+only uses colors if output is directed to a terminal (window).
+These colors might indicate that a critical occupation percentage has
+been reached (red) or has been almost reached (cyan) for a particular
+resource.
+See the man-page of
+.B atop
+for a detailed description of this feature (section COLORS).
+.br
+With the flag
+.B -C
+colors will always be used, even if output is not directed to a terminal.
+.PP
+.TP 5
+.B -M
+Use markers at the end of a line to indicate that a critical occupation
+percentage has been reached ('*') or has been almost reached ('+')
+for particular resources. The marker '*' is similar to the color red
+and the marker '+' to the color cyan. See the man-page of
+.B atop
+for a detailed description of these colors (section COLORS).
+.PP
+.TP 5
+.B -H
+Repeat the header line within a report for every
+.I N
+detail lines. The value of
+.I N
+is determined dynamically in case of output to a tty/window (depending
+on the number of lines); for output to a file or pipe this value is 23.
+.PP
+.TP 5
+.B -R
+Summarize
+.I cnt
+samples into one sample. When the logfile contains e.g. samples of 10 minutes,
+the use of the flag '\-R 6' shows a report with one sample for every hour.
