JMX metrics in 3.3.5

[Levente Laszlo]

Hey Folks,

we upgraded our production instance from 3.2.10 to 3.3.5 recently, running gerrit in a container (ubuntu 20.04)

during the testing of 3.3.5 on my local VM I could see all metrics through JDK mission control, but in production now we can collect only a subset of the previously available metrics. E.g. git/ and sshd/ are completely missing, notedb has only external_id_update_count 

I know that the metrics-reporter-jmx plugin isn't built on stable-3.3, so I downloaded the last stable build from stable-3.2, but again, I've tested it with v3.3.5 and it was OK

So, my question: is there any place (except the plugin config file, which is not used by us) where we can exclude metrics, because I cannot find a hint in the docs?

(extra question: based on the plugin compatibility matrix, metrics-reporter-jmx is not deprecated, is it on the roadmap to add it to stable-3.3 (and stable-3.4)?)

Thanks,

Levente

just as a heads-up, after a container restart, all metrics are available again

Could you please provide any info about the JMX plugin status on stable-3.3?

Thanks,

Levente

Looks like you are affected by the issue which I fixed in this change [1]. This fix is only available in the master branch.

We build that plugin from its master branch and use it for our 21.6 and 3.2 Gerrit servers.

I suggest you also switch to using the build form the master branch.

Thanks,

Levente
