In this chapter, we will discuss performance and discover how vSphere administrators can monitor the resource usage of different inventory objects. It is important to monitor the vSphere infrastructure to determine if there is a resource bottleneck or if a virtual machine or ESXi host is experiencing constraint. There are many tools that are available within vSphere that can assist VMware administrators to monitor resources and detect any potential bottlenecks. Both esxtop
and performance charts are natively available within vSphere for monitoring. Alarms may also be configured to alert administrators when specific events occur or when thresholds are exceeded. In this chapter, you will learn about:
CPU performance considerations
Memory performance considerations
Network performance considerations
Storage performance considerations
Resource controls
vSphere performance charts
