Monitoring in Azure goes well beyond IaaS VMs and I felt it’s worth mentioning. Azure has an entire Application Performance Management (APM) suite called “Application Insights” which lets you monitor live web application traffic and automatically detect performance anomalies as well as offer tools to help you diagnose issues and user behaviors.

In addition, there is a framework called Log Analytics as part of Microsoft’s Operations Management Suite (OMS) that help you monitor not only your cloud environment, but also your on-premises environment. This illustration taken from Microsoft’s documentation shows how VM Agents and storage accounts in Azure can feed into the Log Analytics framework as well as your on-premises environment with System Center Operations Manager (SCOM). This gives you a unified solution across cloud and on-premises to manage monitoring and alerting in your environment.

One other major suite released recently is Azure Monitor. This gives you even deeper monitoring insight in your environment. For example you can now monitor not only the Guest OS of an Azure VM, but also you gain monitoring capability of the Host VM. It’s definitely worth exploring all these options.
