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
