Description

Hi,
I am trying to send the Datatype and description of metric types via exporter prometheusremotewrite
I have enabled send_metadata: true but I don't see any changes.

I have added the logging exporter and do see the DataType:

Metric #17                                                                                                                                                                                                                                                                 │

Could you please try to upgrade to the latest version of the exporter?
Also do you see any errors in the logs of either otel collector or mimir?
Another thing you could try is sending OTLP directly to mimir see if that helps.

[bote795]

Don't see any errors in the logs for either, but let me try upgrading and see if that makes a difference

It seemed that it was just a cache issue on the Grafana UI. It was working. Thanks for the help!
