Hi Farhane,

One option to implement that would be too add code that collects the required data to the `execute` function of the data collector: https://github.com/beloglazov/openstack-neat/blob/master/neat/locals/collector.py#L188 The current implementation of Neat is not relying on Ceilometer, as it appeared after Neat had been developed. You may be able to fetch the necessary data from Ceilometer directly in local or global manager skipping the data collector completely; however, you would need to investigate that.

Best regards,
Anton
