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

Warning

Ceilometer's native storage has extremely large resource requirements. For more efficient time-series storage, a time-series database such as Gnocchi is recommended. The following instructions are unsupported in future releases.

Before you install and configure the Telemetry service, you must create a database, service credentials, and API endpoints. However, unlike other services, the Telemetry service uses a NoSQL database. See environment-nosql-database-obs to install and configure MongoDB before proceeding further.

Create the ceilometer database:

# mongo --host controller --eval '
  db = db.getSiblingDB("ceilometer");
  db.addUser({user: "ceilometer",
  pwd: "CEILOMETER_DBPASS",
  roles: [ "readWrite", "dbAdmin" ]})'

MongoDB shell version: 2.4.x
connecting to: controller:27017/test
{
 "user" : "ceilometer",
 "pwd" : "72f25aeee7ad4be52437d7cd3fc60f6f",
 "roles" : [
  "readWrite",
  "dbAdmin"
 ],
 "_id" : ObjectId("5489c22270d7fad1ba631dc3")
}

Replace CEILOMETER_DBPASS with a suitable password.

Note

If the command fails saying you are not authorized to insert a user, you may need to temporarily comment out the auth option in the /etc/mongodb.conf file, restart the MongoDB service using systemctl restart mongodb, and try calling the command again.

Install and configure components

Install the packages:

# zypper install openstack-ceilometer-api \
  openstack-ceilometer-collector \
  openstack-ceilometer-agent-notification \
  openstack-ceilometer-agent-central python-ceilometerclient

Configure the Apache HTTP server

Note

The following is only required if Ceilometer's native storage is enabled.

Create the /etc/apache2/conf.d/wsgi-ceilometer.conf file with the following content:

Listen 8777

<VirtualHost *:8777>
    WSGIDaemonProcess ceilometer-api processes=2 threads=10 user=ceilometer group=ceilometer display-name=%{GROUP}
    WSGIProcessGroup ceilometer-api
    WSGIScriptAlias / "/var/www/cgi-bin/ceilometer/app"
    WSGIApplicationGroup %{GLOBAL}
    ErrorLog /var/log/apache2/ceilometer_error.log
    CustomLog /var/log/apache2/ceilometer_access.log combined
</VirtualHost>

WSGISocketPrefix /var/run/apache2

Finalize installation

Reload the Apache HTTP server:
```
# systemctl reload apache2.service
```

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