zigomrunge: Hi there! Are you around?11:25
zigoI'm trying to add a custom dynamic pollster, I believe I did the polling.yaml + /etc/ceilometer/pollsters.d definition correctly, as the logs look like showing it works.11:26
zigoHowever, I wonder: do I also need to write /etc/ceilometer/meters.yaml ?11:26
zigoIn  /etc/ceilometer/meters.d probably?11:27

mrungezigo, hey, I am somewhat around13:42
mrungelet me read back13:42
zigo:)13:42
mrungeokay, personally, I don't have any experience with dynamic pollsters13:43
zigomrunge: NV, thanks.13:57
zigomrunge: I sent a mail to Julien Danjou to ask him about it.13:58
zigomrunge: Did you settle on a backend for timeseries, what's the roadmap for telemetry?13:59
zigoI did a setup with dedicated physical nodes for the notification bus, and a dedicated Ceph. It's working very well, but it's kind of overkill (ie: 12 physical servers...).14:00
mrungethe dynamic pollster feature is something which came after Julien left14:01
mrungethe decision on getting rid of gnocchi (or not) was somewhat delayed. When we were to talk about that, gnocchi proponents were there and described how satisfied they are14:02
mrungebut... nobody wants to maintain it14:02
mrungeI'm glad to hear it works well for you14:03

zigomrunge: It works well because I took care of provisionning a large infra for it, though I'd be glad to reduce that to half of the hardware if it becomes possible.14:46
zigomrunge: Do you know who wrote the dynamic pollster stuff?14:46
zigoCurrently, in my agent-notification logs, I have:14:47
zigo2021-03-02 14:42:43.786 32708 DEBUG ceilometer.publisher.gnocchi [-] Processing sample [<name: network.ports.ext-net1, volume: 1, resource_id: c558857c-d010-41ba-8f93-08c3cb876ebe, timestamp: 2021-03-02T14:42:43.570481>] for resource ID [c558857c-d010-41ba-8f93-08c3cb876ebe]. publish_samples /usr/lib/python3/dist-packages/ceilometer/publisher/gnocchi.py:34414:47

zigoSo it looks like the pollster is posting the data to rabbit, then the notification agent gets it, but doesn't know it must post data to Gnocchi ...14:47
zigo(ie: 0 measures posted against 0 metrics through 0 resources)14:48
mrungeDynamic pollster was written by Raphael Weingartner14:48
zigoThanks, I'll try to ask him then.14:50
zigoRafael Weingärtner14:52
zigoNo ph in Rafael.14:52
