Installing Telemetry in OpenStack

In this section, we will include the Telemetry module in OpenStack. For the sake of simplicity, we will install the following Telemetry components using the command-line interface in the cloud controller node:

• Ceilometer with a legacy storage backend
• Aodh for alarm notification and evaluation

The Ceilometer installation

The next steps show how to install Ceilometer in our existing environment. We will first begin by configuring our controller node, cc01.packtpub:

1. Install the core components described previously:

    # yum install openstack-ceilometer-api openstack-ceilometer-
    collector openstack-ceilometer-central python-ceilometerclient

2. Install MongoDB, which Ceilometer needs for the backend database:

    # yum --enablerepo...
