Enable Compute service meters for Red Hat Enterprise Linux and CentOS

Telemetry uses a combination of notifications and an agent to collect Compute meters. Perform these steps on each compute node.

Install and configure components

  1. Install the packages:

    # dnf install openstack-ceilometer-compute
    # dnf install openstack-ceilometer-ipmi (optional)

Finalize installation

  1. Start the agent and configure it to start when the system boots:

    # systemctl enable openstack-ceilometer-compute.service
    # systemctl start openstack-ceilometer-compute.service
    # systemctl enable openstack-ceilometer-ipmi.service (optional)
    # systemctl start openstack-ceilometer-ipmi.service (optional)
  2. Restart the Compute service:

    # systemctl restart openstack-nova-compute.service
