Configure Azure Monitor Alerts and Action Groups for App Service

Azure Monitor provides a unified alerting platform that detects issues across cloud infrastructure and applications before they impact end users. Alerts evaluate telemetry data - platform metrics, resource logs, and activity logs - against defined conditions and trigger automated responses through action groups, enabling operations teams to maintain service reliability at scale.

In this lab, you will configure diagnostic settings on a pre-provisioned App Service to send logs to a Log Analytics workspace, create an action group with email notification channels, build a metric alert rule that monitors CPU percentage against a defined threshold, and create a KQL-based log search alert that detects HTTP server errors.

Objectives

Upon completing this intermediate level lab, you will be able to:

• Configure diagnostic settings on an App Service to stream logs to a Log Analytics workspace
• Create an action group with email and webhook notification types
• Create a metric alert rule that monitors App Service Plan CPU percentage against a static threshold
• Create a log search alert rule using a KQL query to detect HTTP 5xx errors

Who is this lab for?

This lab is designed for:

• Cloud engineers and administrators preparing for AZ-104 or AZ-500 who need hands-on experience with Azure Monitor alerting
• DevOps engineers looking to implement proactive monitoring and automated notification workflows
