Hi @rjlce could you share the whole terraform script you are using? I will try to reproduce it on my end as well.

Hi @Chambras,

Thanks very much for the support! I've attached a sample terraform script where the issue is occurring. I am running it via terragrunt, but only using terragrunt to set up the root configurations. I've included the terragrunt file as well for your reference.

I've redacted any sensitive information, but I assume you can fill that information in for testing on your end.

Also, below are screenshots showing that the output from running the terraform indicates that severity will be set to 0, but once it's created, it shows severity is set to 4 in the Azure portal.

Please let me know if you need any additional information.

Thanks again!

Hi @Chambras,

A friendly follow-up to see if you had any updates on this. My team is managing multiple prometheus rule groups across different Azure Monitor Workspaces using the terraform, but this bug is a pretty big burden since anytime we re-apply our terraform, we have to go into the Azure portal and manually re-update the severity from Sev4 to Sev0 for any Sev0 alerts.
