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 resource and its metrics:

   $ gnocchi resource list  --type image

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:

   $ gnocchi measures show 839afa02-1668-4922-a33e-6b6ea7780715
   +---------------------------+-------------+-----------+
   | timestamp                 | granularity |     value |

   +---------------------------+-------------+-----------+
   

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

   $ rm /tmp/cirros.img
