Tackling esxtop for VMware performance management prowess

While the vSphere client provides performance data, the esxtop and resxtop performance utilities offer more advanced information to ease virtualization troubleshooting efforts. In this tip, we focus on using esxtop and resxtop; but the same performance statistics can be viewed from the vSphere client. Esxtop and resxtop run in a shell session, and manual coding can be intimidating. But don’t let the format discourage you. Once you get used to the controls and how to interpret the data, these tools become invaluable for reading how CPUs handle the workloads of hosts and virtual machines (VMs).

Esxtop vs. resxtop

While esxtop runs only inside an ESX service console — either directly at the console or remotely using a secure shell console –resxtop is a remote version of esxtop. Resxtop is included in the Linux version of the vSphere command line interface (CLI) and is part of the vSphere Management Assistant (vMA). Esxtop and resxtop function the same way and provide the same information, but resxtop supports only the interactive and batch modes and cannot be run in replay mode.
