Using resxtop for Performance Monitoring
The resxtop vCLI command allows you to examine how ESXi systems use resources. You can use the command in interactive mode (default) or in batch mode. The Resource Management documentation explains how to use resxtop and provides information about available commands and display statistics.
If you cannot reach the host with the resxtop vCLI command, you might be able to use the esxtop command in the ESXi Shell instead. See Getting Started with vSphere Command-Line Interfaces for information on accessing the shell.
Important resxtop and esxtop are supported only on Linux.
