Instrumentation infrastructure for plugins

[deadtrickster]

Add API so plugins can instrument themselves, just like main Elli does. Something generic, or just use Prometheus/Prometheus data model?

[yurrriq]

👍 for generic, but skewing Prometheus-friendly.

Any new thoughts on this?

[tsloughter]

I don't understand what this means.

[yurrriq]

I think the idea is to codify and expose an API for calculating timings, as we do internally, such that a middleware can do the same to instrument itself, without having to reimplement anything... if that makes sense.

[tsloughter]

Ah ok, that is how I took it at first too but not sure how that relates to prometheus? We are just talking about the timing and size atoms, like those that already exist?

Should we consider Open Telemetry for this? I wouldn't mind working on it, but:

1. I need to know what timings we're interested in (all of them?)
2. if I could come up with the scope and name for the telemetry events or if there's ideas around those already...
