Description

What is the bug?

The recording rule is somehow misconfigured. It's query returns no data. This results in the latency panels in Mimir / Write dashboard showing no data, as they use the rule.

Looking at the requests, it seems setting the rate from 1m up to 2m or more, does retrieve data.

How to reproduce it?

  1. Deploy Mimir distributed Helm chart
  2. Install pre-compiled mixins in Grafana.
  3. Execute query for the recording rule, retrieving no data.
  4. verify the recording rule query works, with higher rate interval (eg. metric does exist)

What did you think would happen?

The recording rule would retrieve proper data for use in the dashboards.

What was your environment?

Deployment Tool: Helm Mimir Chart version: 5.8.0 Mimir App version: 2.17.0 Mimir mixins precompiled version: 2.17.0 Grafana version: 12.1.1

Any additional context to share?
