Hi, I have found that filter model for Events has mandatory parameters start_time and end_time of the events period. So, it seems that structure for rowkey as ''timestamp + event_id" will be more suitable. I have started to work on bp https://blueprints.launchpad.net/ceilometer/+spec/hbase-events-feature Partial implementation of events into HBase is available by link https://review.openstack.org/#/c/91408/ By now it was added record method that writes events into HBase and get method with filtering by period of generation time of events.
