Azure Monitor
A platform that collects, analyzes, and acts on telemetry from Azure and on-premises resources.
Azure Monitor is the unified observability platform that ingests metrics (numerical time-series data) and logs (structured records) from Azure resources, on-premises systems, and other clouds. It stores logs in a Log Analytics workspace, where Kusto Query Language (KQL) queries power dashboards, workbooks, and alert rules; metric alerts fire near-real-time while log alerts run on scheduled queries. The exam distinction is that Azure Monitor is the umbrella service, with Log Analytics, Application Insights, VM Insights, and the Alerts engine as components within it. Azure Service Health, by contrast, reports Microsoft’s infrastructure status rather than your own resource telemetry.
