 Azure Monitor collects and aggregates the data from every layer and component of your system into a common data platform. It correlates data across multiple Azure subscriptions and tenants, in addition to hosting data for other services. Because this data is stored together, it can be correlated and analyzed using a common set of tools. The data can then be used for analysis and visualizations to help you understand how your applications are performing and respond automatically to system events.

-## Monitoring and observability

-Observability is the ability to assess an internal system’s state based on the data it produces. An observability solution analyzes output data, provides an assessment of the system’s health, and offers actionable insights for addressing problems across your IT infrastructure.

-Observability wouldn’t be possible without monitoring. Monitoring is the collection and analysis of data pulled from IT systems.

-The pillars of observability are the different kinds of data that a monitoring tool must collect and analyze to provide sufficient observability of a monitored system. Metrics, logs, and distributed traces are commonly referred to as the pillars of observability. Azure Monitor adds “changes” to these pillars.

-When a system is observable, a user can identify the root cause of a performance problem by looking at the data it produces without additional testing or coding.
-Azure Monitor achieves observability by correlating data from multiple pillars and aggregating data across the entire set of monitored resources.
