How to monitor Microsoft Azure VMs

This article discusses the monitoring of Azure virtual machines (VMs) and provides an overview of key metrics to track their health and performance. It focuses on Infrastructure-as-a-Service (IaaS) deployments, where Azure's basic compute resource is the VM. The four main types of metrics discussed are CPU usage, disk I/O, memory utilization, and network traffic. For each metric type, specific examples of relevant metrics are provided along with their descriptions and metric types. Additionally, the article suggests which metrics to alert on for each type. The conclusion emphasizes that monitoring these general-purpose metrics will provide a high-level view of VMs' health and performance, while specialized metrics may be needed over time depending on specific applications.
