Azure Monitor Alert Processing & Routing Pipeline

Alert rules in Azure Monitor are the foundation of proactive monitoring. They define the conditions—such as a metric crossing a threshold or a log query returning a specific result—that trigger alerts. When an alert fires, the rule determines what happens next by specifying one or more action groups and optionally linking to alert processing rules. You can create alert rules manually for any Azure resource, or you can use Recommended Alerts to quickly enable predefined rules for a supported service. A more scalable approach is Azure Monitor Baseline Alerts (AMBA), which provides product-group and field-tested alert definitions for compute, networking, and Service Health resources. AMBA ships as deployable ARM, BICEP, or policy definitions, making it easier to enforce consistent alerting across many resources at once.
