Verify operation¶

Verify operation of the Telemetry service. These steps only include the Image service meters to reduce clutter. Environments with ceilometer integration for additional services contain more meters.

1. Source the admin credentials to gain access to admin-only CLI commands:

   $ . admin-openrc
   

2. List available meters:

   $ ceilometer meter-list
   +--------------+-------+-------+--------------------------------------+---------+------------+
   | Name         | Type  | Unit  | Resource ID                          | User ID | Project ID |
   +--------------+-------+-------+--------------------------------------+---------+------------+
   | image        | gauge | image | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   | image.size   | gauge | B     | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   +--------------+-------+-------+--------------------------------------+---------+------------+
   

3. Download the CirrOS image from the Image service:

   $ IMAGE_ID=$(glance image-list | grep 'cirros' | awk '{ print $2 }')
   $ glance image-download $IMAGE_ID > /tmp/cirros.img
   

4. List available meters again to validate detection of the image download:

   $ ceilometer meter-list
   +----------------+-------+-------+--------------------------------------+---------+------------+
   | Name           | Type  | Unit  | Resource ID                          | User ID | Project ID |
   +----------------+-------+-------+--------------------------------------+---------+------------+
   | image          | gauge | image | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   | image.download | delta | B     | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   | image.serve    | delta | B     | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   | image.size     | gauge | B     | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   +----------------+-------+-------+--------------------------------------+---------+------------+
   

5. Retrieve usage statistics from the image.download meter:

   $ ceilometer statistics -m image.download -p 60
   +--------+---------------------+---------------------+------------+------------+------------+------------+-------+----------+----------------------------+----------------------------+
   | Period | Period Start        | Period End          | Max        | Min        | Avg        | Sum        | Count | Duration | Duration Start             | Duration End               |
   +--------+---------------------+---------------------+------------+------------+------------+------------+-------+----------+----------------------------+----------------------------+
   | 60     | 2015-04-21T12:21:45 | 2015-04-21T12:22:45 | 13200896.0 | 13200896.0 | 13200896.0 | 13200896.0 | 1     | 0.0      | 2015-04-21T12:22:12.983000 | 2015-04-21T12:22:12.983000 |
   +--------+---------------------+---------------------+------------+------------+------------+------------+-------+----------+----------------------------+----------------------------+
   

6. Remove the previously downloaded image file /tmp/cirros.img:

   $ rm /tmp/cirros.img
