Andrew Kelleher has done a fantastic job with his guide on using Log Analytics for Azure Policies. His clear and practical approach makes complex concepts easy to grasp.

Here are 3 key takeaways:

1. CUSTOM TAGGING POLICY CREATION AND ASSIGNMENT

Implementing a custom tagging policy in Azure allows for specific auditing, such as checking for missing tags on resource groups. To do this, you define and create a custom tagging policy using a JSON template, and then assign it at the subscription level to ensure it checks all relevant resource groups. This process might need to be repeated for different tags and subscriptions to cover all necessary aspects.

2. LOG ANALYTICS INTEGRATION AND QUERY FORMULATION

By connecting the Azure Activity Log to a Log Analytics workspace, you can leverage the alerting capabilities of Log Analytics to monitor for non-compliant resource groups. The key is to develop an effective Log Analytics query that can identify these non-compliant resources, which involves specifying the operation name and properties related to the audit of resource group tags.

3. ALERT CONFIGURATION AND TESTING

Once the Log Analytics query is established, configure an alert rule in Log Analytics to trigger notifications for any detected non-compliance. This involves setting parameters such as the threshold and frequency of the checks. Testing the alert rule ensures that it correctly identifies non-compliant resource groups and sends notification emails, thereby enabling timely remediation actions.

Thanks to Andrew, many we will benefit from implementing these effective solutions in Azure. Great work!
