Performance Monitoring Utilities: resxtop and esxtop

The resxtop and esxtop command-line utilities provide a detailed look at how ESXi uses resources in real time. You can start either utility in one of three modes: interactive (default), batch, or replay.

The fundamental difference between resxtop and esxtop is that you can use resxtop remotely, whereas you can start esxtop only through the ESXi Shell of a local ESXi host.
