Azure Monitor is a comprehensive monitoring solution for collecting, analyzing, and responding to monitoring data from your cloud and on-premises environments. You can use Azure Monitor to maximize the availability and performance of your applications and services. It helps you understand how your applications are performing and allows you to manually and programmatically respond to system events.

Azure Monitor collects and aggregates the data from every layer and component of your system across multiple Azure and non-Azure subscriptions and tenants. It stores it in a common data platform for consumption by a common set of tools which can correlate, analyze, visualize, and/or respond to the data. You can also integrate additional Microsoft and non-Microsoft tools.
