Alert processing rules (formerly action rules) provide post-processing capabilities for fired alerts in Azure Monitor, such as scheduled suppression and at-scale actions management. Following the updated public preview from December 2021, this feature is now generally available.
As part of the generally available announcement, we will be retiring the existing preview APIs of alert processing rules / action rules in June 2022, so update your environments accordingly. This includes ARM templates / PowerShell / CLI etc. We will also start to enforce a per subscription quota on the rules (1000 rules per subscription). See the limits document for more details.
Action required: Update your environments such as ARM templates / PowerShell / CLI etc. as soon as possible, as we will be retiring the existing preview APIs of alert processing rules / action rules in June 2022,
