API Version

0.24

SDK Version

0.24

What Exporter(s) are you seeing the problem on?

Prometheus

Relevant log output

I'm also running into it. We could raise a PR bumping to opentelemetry 0.24, but I'm not really sure if it will be accepted, given #1792 said

Also removed opentelemetry-prometheus from CI for now, as it is not planned for the upcoming release : #1719

[mellowagain]

we're actually also running into this with autometrics (autometrics-dev/autometrics-rs#179). on the readme for the exporter it does say

The development of prometheus exporter has halt until the Opentelemetry metrics API and SDK reaches 1.0. Current implementation is based on Opentelemetry API and SDK 0.23.

so that also speaks for that a pr to bump it wouldn't be accepted. i couldn't find any reasoning behind stopping development on the prometheus exporter, is there more reading into why?

I guess let's just give it a try :) I did the needed changes and created #1957

Tested them using the following Cargo.toml and it seems to work

[patch.crates-io]
opentelemetry-prometheus = { git = "https://github.com/sbernauer/opentelemetry-rust", branch = "feat/otel-prom-0.17.0" }

@sbernauer wow, I also made a workaround 2 days ago

[patch.crates-io]
opentelemetry-prometheus = { git="https://github.com/ttys3/opentelemetry-rust.git", branch="opentelemetry-prometheus-sdk-0.24" }
