What happened:

In case if a request to Azure Monitor / Azure Management API endpoint failed with an error, Grafana logs do not provide any insight other than status code.

What you expected to happen:

Grafana should log error response (at least error message) from the data endpoint, so the logs could be captured and analyzed.

How to reproduce it (as minimally and precisely as possible):

Current log output looks like this:

INFO [11-21|21:20:52] Request Completed                        logger=context traceID=00000000000000000000000000000000 userId=123 orgId=1 [email protected] method=GET path=/api/datasources/2/resources/azuremonitor/subscriptions status=401 remote_addr=[xxx] time_ms=233 duration=233.6361ms size=76 referer=http://yyy/datasources/edit/uaCMDFqGk traceID=00000000000000000000000000000000 handler=/api/datasources/:id/resources/*

Anything else we need to know?:

A customer reported a problem with authentication in Azure Monitor datasource and there's no way to investigate the problem on our side because Grafana doesn't log any details.

Environment:

• Grafana version: main
• Data source type & version: Azure Monitor
• OS Grafana is installed on:
• User OS & Browser:
• Grafana plugins:
