OTLP gRPC output – support for `X-Scope-OrgID

[laitm]

Hi,

I'm currently testing the native OTLP output in gNMIc and wanted to check whether it supports sending custom headers, specifically the X-Scope-OrgID header.

In my setup, the OTLP endpoint requires the X-Scope-OrgID header for multi-tenant identification (for example when sending data to Grafana Mimir/Loki/Tempo).

During my testing, I'm not seeing the X-Scope-OrgID header being included in the outgoing OTLP gRPC requests,

Question:
Does the gNMIc OTLP gRPC output support configuring custom headers such as:

X-Scope-OrgID: <tenant-id>

If it is supported:

• Is there a specific configuration field to define additional request headers?
• Could you share an example configuration?

If it is not currently supported, would this be something that could be considered for future support?

Thanks!

Hi, not supported today but can easily be added.

I would be very grateful if it could be added in a subsequent release as currently a blocker.
