GenServer instrumentation (helper)

[tombruijn]

Provide an easy one-two line solution to instrumenting GenServers.

For example by (only) including a module:

defmodule Foo do
  use GenServer
  use Appsignal.Instrumentation.GenServer

  # GenServer implementation
end

As reported here (private link)

Yes, would be definitely nice to have

Let's get back to it if someone asks for it again. Closing for now.

Well, pretty timely closure 😅 I am evaluating AppSignal, I make a lot of use of background GenServers in my app, and landed on this issue while googling for the best way to instrument a process.

A helper module I can just use would certainly help for the smaller background processes, while the bigger ones will require hand-written instrumentation.

@1player Pretty timely comment on your end as well! We closed this because we were unsure if there was enough interest in it -- we can reconsider this decision.

Part of the reason we closed this is that we are unsure of what a good GenServer instrumentaton would look like. Would you be interested in trying out a proof of concept for it and giving us feedback? If so, please reach out to us at [email protected], and mention this issue on your message.
