Monitoring Virtual Machines with Azure Monitor

What Azure Monitor is

Azure Monitor is a comprehensive cloud monitoring service that maximizes the availability and performance of applications and services by delivering a complete platform for collecting, analyzing, and acting on telemetry from cloud and on-premises environments.

How it meets the requirements

Azure Monitor collects and aggregates metrics (numerical values describing performance at specific points in time) and logs (timestamped records of system events) from Azure virtual machines. It provides built-in tools such as Metrics Explorer and Log Analytics to analyze system health. Furthermore, Azure Monitor alerts proactively notify administrators via email, SMS, or automated actions when metrics exceed predefined thresholds, such as high CPU, memory saturation, or VM unavailability.

Key advantages and capabilities

• Unified data platform: Aggregates platform metrics, resource logs, and activity logs in a single central repository.
• Near real-time metric alerts: Evaluates resource performance at regular intervals and rapidly triggers notifications before users experience outages.
• Advanced log analysis: Uses the Kusto Query Language (KQL) within Log Analytics to query complex event logs across multiple virtual machines.
• Curated insights: Features specialized tools such as VM insights to map processes and dependencies across Windows and Linux environments.
• Flexible visualization: Supports customizable Azure Dashboards, Workbooks, and integrations with Power BI or Grafana.

Why this is optimal

Azure Monitor provides native, built-in telemetry collection and automated threshold alerting for Azure virtual machines without requiring third-party management tools, making it the ideal foundational monitoring solution.
