Investigate how to report metrics from workspaces

[mkuznyetsov]

It is needed to figure out the approach on how to collect and observe metrics from workspace agent/editor/language servers, such as "The % of workspaces projects cloned successfully" and "The % of Language Servers requests that get a successful response"

related to #13270

Duplicate of Investigate Language server metrics #14017 ?

[skabashnyuk]

I think they can be distinct.
#14017 - can be limited to providing metrics in Prometheus format to some endpoint.
#13375 - this can be about how to collect LSP and other metrics from the workspace and deliver them to Prometheus server

[tsmaeder]

So we need to wait now until this issue here is solved?

[skabashnyuk]

I think you can start working #14017

[tsmaeder]

We're going to have metrics from theia plugins soon. Any progress on this issue?

Any progress on this issue?

No. No progress.
The only known to me reasonable variant is to relay on prometheus-operator. However, for hosted Che it can be a complicated dependency.
