Install and configure for Red Hat Enterprise Linux and CentOS

This section describes how to install and configure the Telemetry service, code-named ceilometer, on the controller node.

This section assumes that you already have a working OpenStack environment with at least the following components installed: Compute, Image Service, Identity.

Prerequisites

Before you install and configure the Telemetry service, you must configure a target to send metering data to. The recommended endpoint is Gnocchi. To enable Gnocchi, please see its install guide.

Install and configure components

1. Install the packages:

   # yum install
     openstack-ceilometer-collector openstack-ceilometer-notification \
     openstack-ceilometer-central python-ceilometerclient

Finalize installation

1. Start the Telemetry services and configure them to start when the system boots:

   # systemctl enable openstack-ceilometer-notification.service \
     openstack-ceilometer-central.service \
     openstack-ceilometer-collector.service
   # systemctl start openstack-ceilometer-notification.service \
     openstack-ceilometer-central.service \
     openstack-ceilometer-collector.service
