Hi Umar, As far as I know, you should follow these steps to make this work: 1- Run stack.sh 2- Add rules to policy.json in /etc/ceilometer 3- Restart ceilometer service. Follow this link [1] to see how can you restart a particular service. [1] http://stackoverflow.com/questions/23593508/restarting-a-service-in-openstack-installed-using-devstack Hope this helps.
