Dropping Metrics in Datadog Exporter

Is your feature request related to a problem? Please describe.

Multiple applications are usually pushed to the same central OTEL collector. I am trying to drop certain metrics via a name match so they would be ignored and not sent to Datadog.

I would ask the same question as well for tags, I want to drop certain high cardinality tags if I see them on ANY (or regex) metric name.

Reading the docs, I don't think this is possible today.

Describe the solution you'd like

• An action to drop certain metrics based on a metric's name regex match in the OTEL Collector yml.
• An action to drop tags via exact name matches in the OTEL Collector yml.

Describe alternatives you've considered

Tried to use the Metric Transform and Attribute Processor but doesn't seem possible as well.

Hi @TRAD-Anthony-CKO, this behavior of dropping metrics would be better suited in a processor as opposed to an exporter. The filter processor should work for this use case, and the transform processor may work for this as well.

Hi @liustanley, thanks for taking the time to respond!

Noted, the filter processor should have those as I saw from the docs. Closing the issue!
