This is on a Newton Packstack. I try to trigger alarms based on average cpu_util of a group of instances. *Problem: *The alarm perpetually remains in state "insufficient data".
Ceilometer is configured to use Gnocchi and the medium archive policy (which stores data once a minute). The intervals in pipeline.yaml are set to 60. I run two instances with high CPU usage. Both have a metadata item "metering.server_group=hicpu". The alarm uses a query "server_group==hicpu", has a granularity of 60 and evalution periods set to 1. I expect it to be in state /alarm /or /ok /after less than 2 minutes. From Gnocchi, I can retrieve measures, both of the two individual instances and of aggregate measures. *Why "insufficient data"? **How can I find out what's going on in Aodh's mind? *More info below. Thanks.
