Hey, I would like to revive this PR. I've found some time to test it out and it does exactly what I need from it to do. At least I think it does. I would appreciate another review and possibly the direction what else should I do to have this PR ready for merge 🙏 . |

Sure, I'll try my best. |

Could you update docs as well to include this metric? |

It's done. Although I'm not sure I chose the right place for it 😄 |
Could you send me the link? I can't find it :( |

Never mind, I mixed up docs and changelog. So I changed the changelog. I'll revert it and edit the docs. Should I add it to version |

I'm not 100% sure, but I think that the name is keda_internal_scale_loop_latency_bucket here
e2e test has failed here

Hmm, I see the problem with otel. There is no otel metric for this. The problem is I don't have enough expertise to create an otel histogram metric 🤔 So we have two options. Remove e2e test or make the otel metric somehow.

I'd say that we should include it also for otel as it has support for histograms:

you have to call the the record function instead of using an observable approach

Aha, now I can see in the code that I tried something, but apparently it's not the right way to do it.

This PR is supposed to add new histogram type of metric for the internal loop latency. This should be more useful when creating the SLIs.
