I was wondering if it's possible to use Open Telemetry Collector as a proxy to collect Prometheus metrics and Loki logs and send to several backend.
I understand it's possible in some situation but I'm not sure if it's still possible with my requirements.
Open Telemetry Collector should ideally authenticate client with basic authentication, assign a "tenant" based on the authenticated user, and then send the request to all backend including the tenant for example as the X-Scope-OrgID expected by a Loki backend.
If this is not possbile I can still include a minimal reverse proxy in front of Open Telemetry Collector doing this job, but Open Telemetry Collector should then forward the received Authorization and X-Scope-OrgID headers to all backend.
Is this a feature of involved receivers and exporters?
Note that X-Scope-OrgID is generally not constant and depends on credentials used.
