How Microsoft Azure Monitor Works and Architecture

How It Works

Azure Monitor collects telemetry data from various sources, including Azure services, on-premises resources, and custom applications. This data is stored in centralized repositories, such as Azure Monitor Logs and Azure Monitor Metrics, for analysis and visualization. Users can query the data using KQL, create alerts, and take action based on insights.

Architecture Overview

1. Data Sources
   • Azure Resources: Collects metrics and logs from Azure VMs, storage accounts, and app services.
   • Applications: Monitors app performance via Application Insights.
   • Custom Sources: Supports integration with custom log files and APIs.
2. Data Collection
   • Metrics: Captures real-time numerical data like CPU usage or request latency.
   • Logs: Collects textual event data, such as error logs and audit logs.
3. Data Storage
   • Log Analytics Workspace: Stores logs for querying and analysis.
   • Metrics Database: Stores time-series metrics for real-time monitoring.
4. Analytics and Visualization
   • Log Analytics: Allows querying logs using KQL.
   • Metrics Explorer: Provides a user-friendly interface for analyzing metrics.
   • Dashboards: Visualizes key performance indicators in a single view.
5. Alerts and Actions
   • Configures alert rules to notify teams or trigger automated workflows using Azure Logic Apps or Action Groups.
