+# Class to serve Ceilometer API with apache mod_wsgi in place of ceilometer-api service.
+#
+# Serving Ceilometer API from apache is the recommended way to go for production
+# systems as the current keystone implementation is not multi-processor aware,
+# thus limiting the performance for concurrent accesses.
+#
+# When using this class you should disable your ceilometer-api service.
+#
+# == Parameters
+#
+# [*servername*]
+# The servername for the virtualhost.
+# Optional. Defaults to $::fqdn
+#
+# [*port*]
+# The port.
+# Optional. Defaults to 8777
+#
+# [*bind_host*]
+# The host/ip address Apache will listen on.
+# Optional. Defaults to undef (listen on all ip addresses).
+#
+# [*path*]
+# The prefix for the endpoint.
+# Optional. Defaults to '/'
+#
+# [*ssl*]
+# Use ssl ? (boolean)
+# Optional. Defaults to true
+#
+# [*workers*]
+# Number of WSGI workers to spawn.
+# Optional. Defaults to 1
+#
+# [*ssl_cert*]
+# [*ssl_key*]
+# [*ssl_chain*]
+# [*ssl_ca*]
+# [*ssl_crl_path*]
+# [*ssl_crl*]
+# [*ssl_certs_dir*]
+# apache::vhost ssl parameters.
+# Optional. Default to apache::vhost 'ssl_*' defaults.
+#
+# == Dependencies
+#
+# requires Class['apache'] & Class['ceilometer']
+#
+# == Examples
+#
+# include apache
+#
+# class { 'ceilometer::wsgi::apache': }
