The ceilometer compute agent interacts with both the public nova API and the hypervisor layer.

The former requires that the appropriate credentials are configured: 

 sudo openstack-config --set /etc/ceilometer/ceilometer.conf DEFAULT os_auth_url http://127.0.0.1:35357/v2.0
 sudo openstack-config --set /etc/ceilometer/ceilometer.conf DEFAULT os_tenant_name demo
 sudo openstack-config --set /etc/ceilometer/ceilometer.conf DEFAULT os_username admin
 sudo openstack-config --set /etc/ceilometer/ceilometer.conf DEFAULT os_password secrete
 sudo service openstack-ceilometer-compute restart

Use the ceilometer CLI to see the instance-related meters: 

  ceilometer meter-list | head -3 ; ceilometer meter-list | grep -E 'cpu|disk|instance'

Pick an active instance: 

 INSTANCE_ID=$(nova list | awk '/ACTIVE/ {print $2}' | head -1)

then view the CPU utilization (%) samples for that instance: 

 ceilometer sample-list -c cpu_util -r $INSTANCE_ID
