Hi We're using Ceilometer with Gnocchi in Rocky release. And we're using cpu_util variable to doing auto scaling on Heat. We known that ceilometer will create its own archive policy in gnocchi, and default value of granularity is 5 minutes. We want change ceilometer's granularity to a minute. Here's our workaround. 1. Edit pipeline.yaml. Since gnocchi has default policy that granularity = 1 second, we change "gnocchi://" to "gnocchi://?archive_policy=high" 2. Edit ceilometer.conf & polling.yaml, change both evaluation_interval (ceilometer.conf) & interval (polling.yaml) to 60. 3. Restart all ceilometer services We tested this workaround but found that it would not work sometimes. And found that the first detection triggered every "o'clock" when created auto scaling at first time. If we want to shrink the granularity time, is our workaround correct? And how is the correct way to do this if not? Many thanks, Eddie.
