@lsfischer are you still interested in this? I think I'll give it a try next week |
|
@xrmx I briefly started a draft PR but haven't found the time to dedicate to it - please feel free to give it a try if you're interested! Let me know if I can assist you in any way |

I've done the API part some times ago here but need to understand how to hook it later. |
|
Then you're in a similar state that I was in my draft :)
Yeah, my understanding is that we need to update the DefaultAggregation here where we're creating the Looking at the JS implementation could also be helpful (open-telemetry/opentelemetry-js#3876) |
Yeah, that was the plan. 🚀 |

Describe the solution you'd like
Last year a new specification for the histogram bucket metric advise API or hint API got merged in the opentelemetry-specification repository: open-telemetry/opentelemetry-specification#3216
This seems to have been implemented by a few languages already (see open-telemetry/opentelemetry-java#5217, open-telemetry/opentelemetry-js#3876, open-telemetry/opentelemetry-erlang#628 and go) but not for python AFAIK
Doing so would alleviate the currently more complex way of setting custom bins on a histogram by creating a
Viewand adding it to the aMeterProviderdecoupling the bins definition from the histogram creation. This would also allow for different histograms under the sameMeterProviderto define different bins seamlessly.If there's consensus around this feature request, I'd be keen to give it a shot!
