ceilometer polling strange behaviour

Hi everybody,

I'm having a strange behaviour polling two sources ( & compute.node.cpu.idle.percent). Both have the interval configured in pipeline.yaml to 30 seconds but I'm getting samples of compute.node.cpu every 60 seconds. Samples for connections are being received at correct interval. AFAIK, compute samples are queried by ceilometer-agent-compute and by ceilometer-agent-central. So is there any difference in how each agent reads pipeline.yaml?

Some info:

Ubuntu Xenial / Mitaka

Ceilometer 6.0.0

Nova 13.0.0

Neutron 8.1.0

Thanks all,

compute.node.cpu.idle.percent is reported by nova through notification, not by ceilometer-compute polling, so its interval is decided by nova.

Hi Shaoman, Thanks for your reply. Is there any place where configure this interval in nova? I only know instance_usage_audit_period to report information about instances.

Regards, Pepe

The report interval used default periodic_task, 60s by default. If you want to have a test, refer to this:
