Azure VM Insights

▲ ▼

description Azure VM Insights Overview

This feature provides deep, OS-level performance metrics for Virtual Machines, going beyond basic CPU/Memory usage. It monitors disk I/O latency, network throughput per interface, and specific OS performance counters. It is essential for capacity planning and diagnosing performance degradation that isn't immediately obvious from high-level resource metrics.

help Azure VM Insights FAQ

What does Azure VM Insights monitor?

Azure VM Insights collects operating-system and virtual-machine performance data beyond basic CPU and memory usage. It can show disk activity and latency, network throughput, and selected OS performance counters.

Can Azure VM Insights help diagnose slow disks?

Yes, disk I/O metrics and latency can show whether storage is delaying an application or server. Comparing those measurements with CPU, memory, and workload timing helps separate a disk problem from a compute problem.

Does Azure VM Insights monitor network traffic?

It can report network throughput by interface, which helps identify overloaded or unexpectedly quiet network paths. The useful level of detail depends on the monitoring agent, operating system, and Azure configuration.

Is Azure VM Insights useful for capacity planning?

Yes, historical performance data can reveal recurring CPU, memory, disk, or network pressure before a virtual machine becomes unreliable. It is most useful when metrics are reviewed over the actual business workload rather than during a short idle period.
