Is your virtual guest experiencing performance problems? In this two-part session, we will explore the proper tools to diagnose the problem in real time, whether it's CPU, RAM, disk, or network resources. We will also teach you how to use ESXTOP and the VMware vSphere Web client to determine whether your issues exist at the virtual guest layer, the VMware ESXi host layer, or the physical resource layer. Part 1 will focus on intrahost compute resources (CPU and RAM). Part 2 will focus on I/O resources (disk and network) and how to determine if storage issues are inside or outside of your ESXi host. Session content is based in part on questions heard most often from vSphere administrators via the VMware training team.
