Usage

To use collectd-ceilometer-plugin in collectd:

Python plugin must be enabled in collectd

collectd must be started
(ex: systemctl start collectd)

local.conf settings

COLLECTD_AODH_SEVERITIES ~~~~~~~~~~~~~~~~~~~~~~~ ("meter" severity) a comma seperated list of pairs, defining meters and the severity of the alarms they will trigger if their value goes above a certain threshold. The meter is generally in the form of "plugin.type" where plugin and plugin type are attributes of the collectd data. There are three severity options available "low", "moderate" and "critical". If this configuration option is left unset for any alarm the default severity is "moderate".

Example: COLLECTD_AODH_SEVERITIES='"<meter>" <severity>, "<meter>" <severity>'

COLLECTD_BRANCH

(<git branch>) Indicates which branch of collectd to checkout before compiling.

Default: collectd-5.7

COLLECTD_CONF_DIR

(directory) Specify a directory where collectd conf files reside. This is required if you use a distro other than Ubuntu or Fedora, or if the config file is in a non default location. This config directory will be created if it doesn't already exist. Default: /etc/collectd/collectd.conf.d (Ubuntu) /etc/collectd.d (Fedora)

COLLECTD_DIR

(directory) Destination of the cloned collectd source code. Default: $DEST/collectd-$COLLECTD_BRANCH/

COLLECTD_INSTALL

(True|False) Indicates whether to install collectd. Set this to False if you are running a pre-built version of collectd or do not want to upgrade installed version.

Default: True

COLLECTD_BATCH_SIZE

Set the amount of samples to be buffered before sending. Default: 1 i.e. no batching/buffering.

CEILOMETER_TIMEOUT

Sets the ceilometer's request timeout. The value is passed in milliseconds. Default: 1000 i.e. 1 sec.

COLLECTD_LOG_FILE

(file) The path of the collectd log file. Default: /opt/stack/logs/collectd.log

COLLECTD_LOG_LEVEL

(debugnoticeerr) All log messages with lower log level than this are going to be filtered out from the log file. Default: info

COLLECTD_CEILOMETER_CUSTOM_UNITS

(meter=unit) a comma seperated list of pairs, defining meters and their units. Allows existing units to be changed and new units to be set for new meters. The "meter" is generally in the form of "plugin.type", where plugin and plugin type are attributes of the collectd data.

Example: COLLECTD_CEILOMETER_CUSTOM_UNITS="<meter> <unit>,<meter> <unit>"

COLLECTD_GNOCCHI_CUSTOM_UNITS

(meter=unit) a comma seperated list of pairs, defining meters and their units. Allows existing units to be changed and new units to be set for new meters. The "meter" is generally in the form of "plugin.type", where plugin and plugin type are attributes of the collectd data.

Example: COLLECTD_GNOCCHI_CUSTOM_UNITS="<meter> <unit>,<meter> <unit>"

COLLECTD_CEILOMETER_ENABLED

(True|False) Toggle whether collectd-ceilometer-plugin is enabled.

Default: False

COLLECTD_GNOCCHI_ENABLED

(True|False) Toggles whether collectd-gnocchi-plugin is enabled.

Default: True

COLLECTD_AODH_ENABLED

(True|False) Toggles whether collectd-aodh-plugin is enabled.

Default: False

COLLECTD_CEILOMETER_VERBOSE

(True|False) Set this to True to make collectd-ceilometer debugging messages visible as info messages. This is useful when running the plugin inside a collectd compiled without debug message support.

Default: False

COLLECTD_GNOCCHI_VERBOSE

(True|False) Set this to True to make collectd-gnocchi debugging messages visible as info messages. This is useful when running the plugin inside a collectd compiled without debug message support.

Default: $COLLECTD_CEILOMETER_VERBOSE

COLLECTD_AODH_VERBOSE

(True|False) Set this to True to make collectd-aodh debugging messages visible as info messages. This is useful when running the plugin inside a collectd compiled without debug message support.

Default: $COLLECTD_CEILOMETER_VERBOSE

COLLECTD_INSTALL_TYPE

(source|binary) Specify whether the collectd installation should use the package manager or install from source.

Default: binary

COLLECTD_REPO

(url) Location of git repo to clone collectd from.

Default: https://github.com/collectd/collectd.git

COLLECTD_PREFIX

(directory) The directory to install collectd under.

Default: /usr/

COLLECTD_ADDITIONAL_PACKAGES

Specify additional packages to be installed before collectd is built/installed. This is useful when building collectd from source it will make sure the packages are installed. Collectd plugins are automatically installed/built if requirements are met, so there is no need for manual installation. A space separates packages.

Example: COLLECTD_ADDITIONAL_PACKAGES="package1 package2 package3"
