Dear Team, Plz help in following issue. While collecting gnocchi aggregates I ran into 400 response from gnocchi due to lack of metrics at that particular point of time. I am unable to fill the metrics with zero values. The cloudkitty rated_data_frames table in the database shows __NO_DATA__ . Here below are the logs *cloudkitty-processor.log* *2019-01-11 17:06:56.334 7207 WARNING cloudkitty.orchestrator [-] [5793054cd0fe4a018e959eb9081442a8] Error while collecting metric volume.size: {u'cause': u'Metrics not found', u'detail': [u'volume.size']} (HTTP 400).
