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.

Prerequisites

Before you install and configure the Telemetry service, you must configure a target to send metering data to. The recommended endpoint is Gnocchi.

Install Gnocchi

Install the Gnocchi packages. Alternatively, Gnocchi can be install using pip:
```
# yum install openstack-gnocchi-api openstack-gnocchi-metricd \
  python-gnocchiclient
```
Note

Depending on your environment size, consider installing Gnocchi separately as it makes extensive use of the cpu.

Finalize Gnocchi installation

Start the Gnocchi services and configure them to start when the system boots:

# systemctl enable openstack-gnocchi-api.service \
  openstack-gnocchi-metricd.service
# systemctl start openstack-gnocchi-api.service \
  openstack-gnocchi-metricd.service

Install and configure components

Install the Ceilometer packages:

# yum install openstack-ceilometer-notification \
  openstack-ceilometer-central

Finalize installation

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

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