podLabelsAsTags support for custom metrics about helm-charts

[ahmed-mez]

Sorry about that, it might be possible to contribute the feature to the envoy project though. @rocketspacer please feel to contact the support team and submit a feature request.

Hi @rocketspacer

You need to enable Origin Detection so the Datadog Agent can add Pod tags to your custom metrics.

To do so, please set datadog.dogstatsd.originDetection to true in your helm values, and set a DD_ENTITY_ID environment variable in your app Pod template

env:
    - name: DD_ENTITY_ID
      valueFrom:
          fieldRef:
              fieldPath: metadata.uid

If you're using an official and recent Dogstatsd client in your app, it will automatically read the value of DD_ENTITY_ID and forward it with the custom metrics to the Agent, which will rely on the value to attach the corresponding Pod tags.

Origin Detection documentation

I'm closing this issue because it is not really related to the Helm chart, but don't hesitate to contact our solutions team to help you configure Origin Detection if needed.

Thanks!

Shouldn't this default to true 😂
@ahmed-mez and by Dogstatsd client you mean the SDK right?

[ahmed-mez]

Hey @rocketspacer which language and client version you're using in your app? I can double check for you if it supports the feature.
Regarding enabling Origin Detection by default, thanks for the feedback! we can reevaluate this in future helm releases.

Thanks!

I'm using Envoy Dogstatsd stats sink

I think it uses a custom implementation, not in the official libraries list :'(

The DD_ENTITTY_ID value is just used to map to the tag dd.internal.entity_id then I might be able to make this work. Thank you for all the help. I appreciate it. 🙇‍♂️
