Implementing a Prometheus Remote Write Exporter for Python

[shovnik]

We are interested in developing a Prometheus remote write push-based exporter, sending metrics data to a Prometheus remote write integrated backend (Cortex specifically) to support exporting OTLP metrics to new endpoints without needing to run an instance of Prometheus.

This remote write exporter adds more interoperability support for the Prometheus protocol which is aligned with OpenTelemetry’s larger project goal to support Prometheus from the get go.

We plan to provide a detailed design doc, test plan and code to support this implementation. Please assign this issue to both @shovnik and @AzfaarQureshi.

@lzchen Can this be moved to the contrib repo since that is where we were recommended to implement the remote write exporter?

@shovnik
Is that what we decided? I thought we were going to place it with the current prometheus exporter so it won't be confusing.

Hi @codeboten ,

I found a weird thing, the Prometheus Remote Write Exporter is only available on version v0.17b0 of opentelemetry-python-contrib. In the newer version, the module just disappeared.

Is the module deprecated? If not please help to bring back it.
Thank you so much. 😄

@WaynePN

It is in the experimental metrics branch

@lzchen is there any future plan on providing a non experimental release?

See open-telemetry/opentelemetry-python-contrib#933 and open-telemetry/opentelemetry-python-contrib#1359. We can only provide the non-experimental release only when the specification reaches stable https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/data-model.md#prometheus-compatibility.
