[exporter/Datadog] - Metric description does not appear in Metric Summary screen

[MacNale]

What happened?

Description

Metric description does not appear in the DataDog Metric Summary screen when ingested using Datadog Exporter.

Steps to Reproduce

1. Read OTLP metrics from the Kafka using Kafka Receiver
2. Configure Batch processor and DataDog exporter
3. Metrics are visible with the metric data as expected. However the metric description is missing.

Java code which exports the metric with the description.
return Metric.newBuilder() .setName(name) .setDescription(description);

Expected Result

Once the metrics are exported using Datadog exporter, then Datadog Metric summary page should display the metrics description.

Actual Result

Collector version

0.62.0

Thanks for the issue @MacNale. You are right that metrics description and metrics units are not currently shown on Datadog except for select metrics such as those from the builtin hostmetrics receiver.

We are tracking this internally; if someone else is also interested in having support for metrics description and/or units please upvote the issue or comment on your use case.

Also, units are not been send to Datadog, do you have estimation when there will be suppot?

[mx-psi]

We are tracking both of these issues internally but we don't have a timeline to share at the moment
