# Install and start **Ceilometer** service in devstack
|
|
#
|
|
# To enable Ceilometer in devstack add an entry to local.conf that
|
|
# looks like
|
|
#
|
|
# [[local|localrc]]
|
|
# enable_plugin ceilometer git://git.openstack.org/openstack/ceilometer
|
|
#
|
|
# By default all ceilometer services are started (see
|
|
# devstack/settings). To disable a specific service use the
|
|
# disable_service function. For example to turn off alarming:
|
|
#
|
|
# disable_service ceilometer-alarm-notifier ceilometer-alarm-evaluator
|
|
#
|
|
# NOTE: Currently, there are two ways to get the IPMI based meters in
|
|
# OpenStack. One way is to configure Ironic conductor to report those meters
|
|
# for the nodes managed by Ironic and to have Ceilometer notification
|
|
# agent to collect them. Ironic by default does NOT enable that reporting
|
|
# functionality. So in order to do so, users need to set the option of
|
|
# conductor.send_sensor_data to true in the ironic.conf configuration file
|
|
# for the Ironic conductor service, and also enable the
|
|
# ceilometer-anotification service. If you do this disable the IPMI
|
|
# polling agent:
|
|
#
|
|
# disable_service ceilometer-aipmi
|
|
#
|
|
# The other way is to use Ceilometer ipmi agent only to get the IPMI based
|
|
# meters. To avoid duplicated meters, users need to make sure to set the
|
|
# option of conductor.send_sensor_data to false in the ironic.conf
|
|
# configuration file if the node on which Ceilometer ipmi agent is running
|
|
# is also managed by Ironic.
|
|
#
|
|
# Several variables set in the localrc section adjust common behaviors
|
|
# of Ceilometer (see within for additional settings):
|
|
#
|
|
# CEILOMETER_PIPELINE_INTERVAL: Seconds between pipeline processing runs. Default 600.
|
|
# CEILOMETER_BACKEND: Database backend (e.g. 'mysql', 'mongodb', 'es')
|
|
# CEILOMETER_COORDINATION_URL: URL for group membership service provided by tooz.
|
|
# CEILOMETER_EVENTS: Set to True to enable event collection
|
|
# CEILOMETER_EVENT_ALARM: Set to True to enable publisher for event alarming
|
|
|
|
# Save trace setting
