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.* meters:
