Unable to split a metric by dimension in Grafana v9.3.1

[Cstack-Krish]

What happened:

1. Installed the kube-prometheus-stack.
2. Port forwarded grafana and accessed the UI.
3. Added Azure Monitor Datasource.
4. Selected a metric of an App Service, the graph was projected as expected.
5. I wanted to split the metric by dimension (Instance).
6. But upon splitting the metric by Instance grafana threw a 400 Bad request.
7. When the split by dimension is removed the metric gets projected.

What you expected to happen:

Environment:

• Grafana version: v9.3.1
• Data source type & version: Azure Monitor
• OS Grafana is installed on: Linux
• User OS & Browser: Windows, Google Chrome
• Grafana plugins: None

Hi @Cstack-Krish,

Thanks for opening this issue.

Could you please provide us with the backend logs (the default location in Linux is /var/log/grafana/grafana.log) so that we can have more information about the error message?

Hi @usmangt
Thank you for the reply, unfortunately, we couldn't find the backend logs at /var/log/grafana as the folder is empty. We verified that the log's path set in the configuration is var/log/grafana itself.

Hello,
Same issue :
Grafana v9.3.0


Those filters corresponds to filters in azure metrics.

@Cstack-Krish @jad-gha this was fixed in #59700 and is available in 9.3.2, can you check if upgrading solves your issue?

@andresmgot v9.3.2 does fix the issue. Thank you
