Install and configure for openSUSE and SUSE Linux Enterprise

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:
```
# zypper 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.
Install the uWSGI packages. The following method uses operating system provided packages. Another alternative would be to use pip(or pip3, depending on the distribution); using pip is not described in this doc:
```
# zypper install uwsgi-plugin-python3 uwsgi
```
Note

Since the provided gnocchi-api wraps around uwsgi, you need to make sure that uWSGI is installed if you want to use gnocchi-api to run Gnocchi API. As Gnocchi API tier runs using WSGI, it can also alternatively be run using Apache httpd and mod_wsgi, or any other HTTP daemon.

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 packages:

# zypper install openstack-ceilometer-agent-notification \
  openstack-ceilometer-agent-central

Finalize installation

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

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