Re: [openstack-dev] [ceilometer][nova] extra Ceilometer Samples of the instance gauge
Regarding the intevals, it can be configured in your pipeline.yaml file. e.g. sources: - name: meter_source interval: 600 -- change this to a smaller one if you like meters: - * sinks: - meter_sink Regards, - Qiming On Wed, Jul 30, 2014 at 02:16:31PM -0400, Mike Spreitzer wrote: In a normal DevStack install, each Compute instance causes one Ceilometer Sample every 10 minutes.

Re: [openstack-dev] [ceilometer][nova] extra Ceilometer Samples of the instance gauge
In a normal DevStack install, each Compute instance causes one Ceilometer Sample every 10 minutes. Except, there is an extra one every hour. And a lot of extra ones at the start. What's going on here? instance is one meter which is generated through both polling and notifications (see *origin* column[1]). when you create/update/delete an instance in Nova, it will generate a set of notifications relating to the instance. Ceilometer listens to those notifications and generates samples from them.
