DCRs

Hi there JillArmourMicrosoft​ & stepashka​, if I understand correctly, you are talking about Data collection rules (DCRs) in Azure Monitor, right? If so, then you could enable diagnostic settings that will help you track DCR metrics and collect log errors and analytics (see https://learn.microsoft.com/en-us/azure/azure-monitor/data-collection/data-collection-monitor). On the same directions, you can also set up alerts to proactively know what went wrong (details on the same link). Lastly, creating automated bulk status checks will help you a lot, either via Azure CLI (az monitor data-collection rule list) or PowerShell (Get-AzDataCollectionRule).

Hope that helps :)
