-title: Controlling the Daemon
----
-
-The main daemon that runs on nodes keeps internal stats and supports reloading of agents and changing
-logging level without restarting.
-
-If you want to reload all the agents without restarting the daemon you can just send it signal *USR1*
-and it will reload its agents.
-
-You can send *USR2* to cycle the log level through DEBUG to FATAL and back again, just keep sending
-the signal and look at the logs.
-
-Reloading agents work in most cases though we recommend a full daemon restart in production use
-due to the nature of the ruby class loading system. If you are changing agent contents and relying
-on the reload behavior you might end up with agents not being in a consistent state.
-
-## Obtaining daemon statistics
-
-The daemon keeps a number of statistics about its operation, you can view these using the _inventory_
-application:
-
-{% highlight console %}
-% mco inventory example.com
- Server Statistics:
- Version: 2.2.0
- Start Time: Mon Sep 24 17:37:28 +0100 2012

-The statistics mean:
-
-|Statistic |Meaning |
-|------------|-------------------------------------------|
-|Start Time |Local time on the node when the daemon started|
-|Collectives |All known collectives this agent responds on|
-|Main Collective |The primary collective|
-|Process ID |The process ID of the mcollectived|
-|Total Messages |Total messages received from the middleware|
-|Messages Passed Filters|Amount of messages that was determined to be applicable to this node based on filters|
-|Messages Filtered |Messages that did not apply to this node|
-|Expired Messages |Received messages that had expired their TTL values|
-|Replies Sent |Not all received messages result in replies, this counts the actual replies sent|
-|Total Processor Time |Processor time including user and system time consumed since start|
-|System Time |System Processor time only|
-
-You can get the raw values using the *rpcutil* agent using the *daemon_stats* action.
