sdanielHi, my previous problem has solved, but I'm struggling with the following: my generateed alarms have state "insufficient data" and no idea why, because the granularity of the alarm is 120, but in gnocchi I can see new measures in every 60 second.15:26
sdaniel(The intervall in the ceilometer is set for 60 )15:27
sdaniel( in the pipeline.yaml. Both in compute and controller also.)15:28
*** gordc has joined #openstack-telemetry15:34
*** yprokule has quit IRC15:35
jd_sdaniel: if you ask Aodh to fetch a granularity that does not exist in Gnocchi, that happens indeed15:35

sdanieljd: I'm lost a little bit. I configured every interval in the pipeline.yaml to 60, the polling is 60, the resource polling is 20, the alarm granuality is 120, and in the gnocchi there are new measures in every 60 sec16:08
sdanieland still insufficient. Did I make something wrong ?16:08
*** jmlowe has joined #openstack-telemetry16:10
gordcsdaniel: what is resource polling?16:12
gordcyou should be setting your alarm granularity to match the granularity of the data you capture in gnocchi.16:12
gordcit seems you want to be changnig the evaluation periods if you want alarm timespan to be 120 vs existing granularity of 60 is gnocchi.16:13
sdanielalarm granuality in aodh has to be match with the granuality of measuresments in gnocchi ?16:14
gordcyes, (if i remember correctly)... aodh alarms do not resample so if the granularity doesn't exist in gnocchi, it won't work.16:15
sdanielgordc: I mean resource_update_interval. I thought, that somehow I can make it faster to recognize when the heat create a new instance, but now I removed this parameter from my ceilometer.conf.16:17
gordcis resource_update_interval a heat option?16:17
gordcoh. that's not related to alarms16:18
gordcthat just defines how often ceilometer attempts to discover new instances to start metering/monitoring.16:19
sdanielyes, I know. I hoped that can make the detection faster and I will leave this insufficient data sooner in alarm state, but it did not help actually16:20
gordcok16:21
*** jmlowe has quit IRC16:21
sdanielgordc, it seems your right (again). After I changed the granuality of the alarm to match gnocchi, it found16:21

*** Tommy-Tom has quit IRC16:23
gordccool cool. i imagine you could add support to resample on a granularity that doesn't exist in gnocchi (gnocchi itself supports this already). the only issue is that the results of resampling are not necessarily precise.16:25

*** dave-mccowan has joined #openstack-telemetry16:50
sdanielgordc: Your right. If somebody would implement it, it just has to be document, that the required granuality has tob equal or more than the granuality in gnocchi, and if more then 1 measures are matched, then the same calculation will be happen than it defined in the alarm itself as expected aggregation.16:52
sdaniel*granularity (misspelling)16:53
sdanielgordc: For sure, I recreated the alarms from heat (like before) and I did not change anything else. How much time needed to leave this insufficient data state ? I'm waiting for around 8 minutes.16:55
gordcsdaniel: depends the granularity in gnocchi, the evaluation_interval in aodh, the polling interval in ceilometer... it's complicated (which is why we have https://github.com/gnocchixyz/gnocchi/issues/71)17:02

sdanielHi again, I think something is still missing. I re-created the alarms via heat (at now I have scale up and down alarms), but I anyhow set aodh,ceilometer and gnocchi, both of them will still in insufficient data state21:16
sdanielThe strange part, that at first I did not change anything, just recreated the heat stack and I waited for the configurated alarms,, but never happened. After that I tried to change the configuration, but I failed.21:17

gordcsdaniel: did you look at how this scenario is tested in gate? what you're describing is basically what the integration gate on every patch is testing.21:22
*** andreykurilin_ has joined #openstack-telemetry21:22
sdanielceilometer.conf: archive_policy = low (in gnocchi the granularity is 5min), pipeline.yaml: every source interval is 300 (5min), polling.yaml: 300, aodh.conf evaluation_interval is also 300,  granularity in the alarm is 30021:22

sdanielUnfortunatelly I could not spend enough time to try this gate tests, but somehow my alarms started work.22:10
sdanielAfter 1 hour after the alarm creation22:11
sdanielIt's much more, than acceptable. If I change the heat template and I have to recreate the stack, then is it possible, that I have to wait 1 hour again, before I can test the alarms. Not sounds good.22:14
gordcsdaniel: uh so i have no idea what your alarm rule is but did you ever just manually query gnocchi to see if the rule is satisfied?22:17
gordcas you said it works, so either aodh is not evaluating it in a timely matter, or the rule was just never satisfied to begin with.22:18
sdanielgordc: usually I did, but in the last hour, I did not. Actually the scaling down alarm became active, because the cpu_util was less then 10 (%) in the last 5 min (granularity 300)22:27

sdanielgordc: Strange part: In gnocchi I can't find cpu_util metric for the one active vms which can be the part of the aggregation22:28
gordcsdaniel: did you set your archive policy to store the minimum number of datapoints for your alarm? i imagnie you should be able to look back at full timeseries22:46
gordcit's possible your user doesn't have right permission. try querying with admin?22:47
