Explanation

vmstat (virtual memory statistics) is the standard Unix/Linux command that reports memory statistics including user and system memory usage, along with process, swap, and CPU activity. It provides snapshots of system performance. The other options (memstat, mstat, memorystat) are not standard Unix commands - they may exist as third-party tools or are completely fictional.
