Hi ,

Thanks for reaching out to Microsoft Q&A.

To create an alert for Managed Identity operations, including turning ON/OFF System-Assigned or User-Assigned Managed Identities for Container Apps or other resources, follow these steps:

1. Enable Diagnostic Settings:
   • Navigate to the Container App in the Azure portal.
   • Go to Diagnostic Settings. Add a diagnostic setting to log Administrative operations to Log Analytics, Event Hub, or Storage Account.
2. Use Azure Activity Logs: The notifications you see are derived from Activity Logs. These logs capture all management operations. To filter for Managed Identity actions:
   • Go to Activity Logs for your Container App or subscription.
   • Use filters like Operation Name (example: Register managed identity, Deregister managed identity, Add user-assigned identity, Remove user-assigned identity).
   • Verify the detailed records for Managed Identity actions.
3. Set Up Alerts:
   • Navigate to Monitor in the Azure portal.
   • Go to Alerts > Create > Alert Rule.
   • Select a Scope: Choose the specific Container App or subscription.
   • Add Condition: Use "Administrative operation" as the signal. Add filters for specific operation names (ex: Register managed identity, Deregister managed identity).
   • Configure Action Groups to send notifications (email, SMS, etc.).
   • Save and enable the alert.
4. Query in Log Analytics: If you're logging diagnostic data to Log Analytics, you can write a KQL query to get specific Managed Identity events:

   AzureActivity | where ResourceProvider == "Microsoft.ManagedIdentity" | where OperationNameValue in ("Register managed identity", "Deregister managed identity", "Add user-assigned identity", "Remove user-assigned identity") | project TimeGenerated, OperationName, Resource, Caller, Status

5. Test the Alert: Enable/disable the Managed Identity to generate a test log and ensure your alert triggers as expected.

This will provide granular alerting and tracking for Managed Identity operations in Container Apps or other Azure resources.
