Detailed Explanation

The vmstat (virtual memory statistics) is a built-in monitoring utility in Linux. [1] The command is used to obtain information about memory, system processes, paging, interrupts, block I/O, disk, and CPU scheduling. Users can observe system activity virtually in real-time by specifying a sampling period.

$ vmstat -n 1
