Enabling and disabling monitoring services

The IBM® Cloud Infrastructure Center monitoring services (also known as telemetry services) includes the ceilometer service and gnocchi service. Those services are disabled by default. This section instructs how to config and manage the monitoring services.

  • The Ceilometer service collects, normalizes and transforms data produced by the IBM Cloud Infrastructure Center services.

  • The Gnocchi service provides a time-series resource indexing, metric storage service that capture the IBM Cloud Infrastructure Center resources and the metrics associated with them.

Note: If you want to use the monitoring services, you must enable and start the monitoring services.

Enable monitoring services

  • To enable the monitoring services, use the following commands:

Note: To get events data, add the following config into the notification section of the ceilometer conf file /etc/ceilometer/ceilometer.conf:

pipelines = event

Note: Start the gnocchi service before the ceilometer service to avoid getting incomplete meter data.

icic-config metering manage-service --enable gnocchi
icic-config metering manage-service --enable ceilometer

Note:

  1. You need to run the corresponding management command from the management node, such as enable, disable, start, restart etc.

  2. After enabling the services, the services restart automatically after the reboot.

  3. If you add pipelines = event after the enablement of the ceilometer services, you need to use the command icic-services ceilometer restart to make changes take effect. Events generated before adding pipelines = event to the ceilometer.conf are missed.

Once, the service is enabled, you are able to check its status by using the icic-services command, for example:

[root@mgmtnode ~]# icic-services ceilometer status
● openstack-ceilometer-notification.service - OpenStack ceilometer notification agent
   Active: inactive (dead)
● openstack-ceilometer-polling.service - OpenStack ceilometer polling agent
   Active: inactive (dead)

Start monitoring service

  • After enabling the monitoring services, use the following command to start the services, it can start the services on both management node and compute nodes.

    icic-services start

Note: This command only starts the services which are not running, it does not affect the running services.

After starting the service, use the icic-services status command to check the services status, to be able to see five monitoring services (openstack-gnocchi-api.service, openstack-gnocchi-metricd.service, openstack-ceilometer-notification.service and openstack-ceilometer-polling.service) running on the management node, and one openstack-ceilometer-polling.service running on seach compute node, for example:

To start the monitoring services separately, run the following command to start the specific service from the management node or each compute node.

/opt/ibm/icic/bin/icic-services <service> start

where <service> is the ceilometer or gnocchi.

Note: You need to log onto the compute node, if you want to start the service on the computer node.

Note: If you want to close the monitoring services, you must stop and disable the monitoring services.

Stop monitoring services

  • To stop the services, use the following commands, it can stop the services on both management node and compute nodes.

    icic-services stop

After stopping the service, use the icic-services status command to check the services status, to be able to see five monitoring services (openstack-gnocchi-api.service, openstack-gnocchi-metricd.service, openstack-ceilometer-notification.service and openstack-ceilometer-polling.service) dead on the management node, and one openstack-ceilometer-polling.service dead on seach compute node, for example:

To stop the monitoring services separately, run the following command to stop the specific service from the management node or each compute node.

/opt/ibm/icic/bin/icic-services <service> stop

where <service> is the ceilometer or gnocchi.

Note: You need to log onto the compute node, if you want to stop the service on the computer node.

Disable monitoring services

  • To disable the monitoring services, use the following commands:

    icic-config metering manage-service --disable ceilometer
icic-config metering manage-service --disable gnocchi

Note: After disabling the services, the services won't restart automatically after the reboot, you are not able to check its status by using the icic-services command.
