Virtualization Performance Monitoring: vCPU Demand, Usage, and Contention

Written by Joe Kozlowicz on Wednesday, June 13th 2018 — Categories: Azure, Cloud Hosting, VMware

When managing a virtualized environment you’ll naturally want to monitor your compute resources such as memory, CPU, storage, and bandwidth in order to keep an eye on any possible performance issues.

We’ve covered monitoring before – like how much information to collect, how granular you need to get, how to check load averages, and configuring vSphere Alarms for resource consumption. Today we’re taking a closer look at CPU performance monitoring in particular.

Often times the CPU is the first potential culprit to check when you encounter a struggling virtual machine. Learn the differences between CPU metrics, some common problems, and best practices for provisioning CPU cores in this blog.
