Alert rules misbehaving (instances appear empty)

Grafana Alerting
1

  • What Grafana version and what operating system are you using?

    • Grafana v12.3.1 in docker Container running over Red Hat Enterprise Linux 9.7

  • What are you trying to achieve?

    • I’m provisioning alerts using yaml files, but his also happens with manually created alerts.

  • How are you trying to achieve it?

    • I created YAML files with all the alert rules (Again, it also happens with Alerts created withing the Grafana interface)

  • What happened?

  • What did you expect to happen?

    • Alerts to be sent to my contact points (Other environments with the same rules work successfully)

  • Can you copy/paste the configuration(s) that you are having problems with?

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.

    • I have not found ANY errors in the Grafana Logs.

  • Did you follow any online instructions? If so, what is the URL?

    • No instructions

I’m at a complete loss here. I have deleted the container and the image, and I see no errors on the logs, so I am not exactly sure on how to troubleshoot this. Thank you for any help or pointers you may provide.

Hi Diego,

The instances should be visible on the Instance tab, would you mind showing the query and alert condition for this alert?

For provisioned alert rules, you can navigate to the Alert rules page, and click Export > with modifications.

This should display the alert rule query and condition. Perhaps, the alert rule condition is missing.

In OSS and Enterprise displaying alert history requires additional configuration as described here.

I reconstructed the environment, and it’s working well. No solution, but thanks @pepecano for your input.
