vmstat reports information about processes, memory, paging, block IO, traps, disks and cpu activity. It’s part of the procps-ng package, a collection of useful utilities for monitoring a system and its processes.
The first report produced gives averages since the last reboot. Additional reports give information on a sampling period of length delay. The process and memory reports are instantaneous in either case.
The vmstat tool is available on most Unix and Unix-like operating systems including Linux, FreeBSD, and Solaris.
This is free and open source software.
