Telemetry error on simple consumer

[PabloHoyo]

I have a kafka consumer loop running on a Dotnet 9 standard BackgroundService. When initializing the consumer, the call to IConsumer.Consume method throws an error.

Telemetry client instance id changed from AAAAAAAAAAAAAAAAAAAAAA to t39ZaOF6RBuiiv7uI2J0Mw

The application is deployed on AWS Kubernetes with an average of 8 pods, each having its own consumer service. In a local environnement everything works fine.

What's going on? Any hint?

Seeing this in dotnet 8 as well.

This log is related to KIP-714. It is not an error but an informational log documenting the telemetry ID that is needed to debug and query metrics on the broker side for specific clients.

The consumer crashing after this log is a separate issue (fixed in PR #4912) that will be addressed in the upcoming release.

To disable this log and entire telemetry itself, you can disable telemetry on the client side by setting enable.metrics.push to false.
