Oh wow, exactly what I was looking for 😅 🙌

can we somehow help to get this shipped? 💪

[solnic]

Thanks for working on this! 🙇🏻 Would you be able to add some basic specs for this too?

[frederikspang]

@solnic I've added two basic specs.
Latency is a bit difficult, without introducing some timecop kind of tool. Which we do have in sentry-ruby, so we could just introduce it here if we wanted to.

[frederikspang]

@solnic After looking at these, I think queue.process may actually replace op: queue.sidekiq instead of being a child span.
They will always be redundant - But we should set origin or some other field to sidekiq, description or name maybe, to differentiate the processor. (ie. using another processor alongside Sidekiq - or doing queries in Sentry UI across applications)

Looks like it needs a changelog too

I've been testing this out and I don't see queue.sidekiq/queue.process. This is what I see instead:

Thanks for adding the specs. I think it would be good to use timecop there actually.

You're right! I changed that after my comment, before your review here:

I'll have a look at the other comments as soon as possible.

[frederikspang]

@solnic I have updated PR with feedback adjusted!

Edit: I see specs are broken. I'll look into that as well!

[frederikspang]

@solnic The specs failing seems related to sidekiq/sidekiq#6430 - Was able to reproduce locally, after clearing Lock file and bundle install again.

Somewhat unrelated to this PR, although it's noisy.

[solnic]

Great job thank you!

Please update to the latest master. I just checked locally and it passes. Once CI is green I'll merge it in.

@solnic Done!
