Thanks @kakkoyun. I see a value in exposing these timings, but I'm not sure the way we track them right now is valuable. Please see the comment I left.

Can we have just label? It will much easier to aggregate, plus we already do that for other statistics, WDYT?

I think also bucket can be adjusted for timeout. BTW What lookup means is quite vague by this help 🤔 Maybe we can be explicit more.

@bwplotka The first version was using a single histogram with labels 8a46f33. Then I decided to change it, just to be consistent with what we already have in here.

BTW What lookup means is quite vague by this help 🤔 Maybe we can be explicit more.

I'm gonna change the name as you suggested and try to clarify the description.

I think also bucket can be adjusted for timeout.

I've put the boundary at the query timeout. Which timeout value is used for this?

Suggested change
Name: "thanos_bucket_store_index_postings_lookup_duration_seconds",
Name: "thanos_bucket_store_index_cachable_fetches_duration_seconds",

I would add cachable to put highlight that it includes cache (:
