Hi https://docs.openstack.org/ceilometer/pike/admin/telemetry-best-practices.html#data-collection
"By default, Telemetry service polls the service APIs every 10 minutes. You can change the polling interval on a per meter basis by editing the polling.yaml configuration file." Some other samples are built when we received nova notification every hour. On Wed, Nov 22, 2017 at 04:30:10PM +0900, Bernd Bausch wrote:
Context: -------- I teach people the basics of telemetry, alarms and autoscaling. I run Ceilometer with a 60 sec polling interval and want to see measures and trigger alarms after 2-3 minutes.
Maybe you changed the polling into the deprecated location. e.g.: pipeline.yaml insteads o polling.yaml ?
My environment is a DevStack cloned from the master branch some two weeks ago. Ceilometer uses Gnocchi as publisher. nova-manage version returns 17 (Queens). Problem: ------- It takes 10 minutes or longer (I have seen over 30 minutes) after instance launch until the instance's measures are posted to Gnocchi. The notification agent log then includes the message "Resource <UUID> created". Before that, there is no trace of that UUID in the log.
That's really looks like the default polling intervals.
Next problem is a lag in publishing measurements: $ date Wed Nov 22 07:16:38 UTC 2017 $ gnocchi measures show --resource-id 4ec5c876-367a-4918-9037-671b5ece3665 cpu_util +---------------------------+-------------+----------------+ | timestamp | granularity | value | +---------------------------+-------------+----------------+ | 2017-11-22T06:00:00+00:00 | 3600.0 | 0.128224536267 | | 2017-11-22T06:48:00+00:00 | 60.0 | 0.1357511344 | ... | 2017-11-22T06:56:00+00:00 | 60.0 | 0.1310314404 | +---------------------------+-------------+----------------+
To looks if samples are waiting in: ceilometer: sudo rabbitmqctl list_queues name messages_ready messages_unacknowledged | grep "^\(notifications\|ceilometer\)" gnocchi: gnocchi status Regards, -- Mehdi Abaakouk mail: sil...@sileht.net irc: sileht
