Which Linux/UNIX command is used for monitoring the performance of system input/output devices?

The iostat command is used for monitoring the performance of system input/output devices on

Linux/UNIX systems. It provides statistics about disk input/output operations and CPU utilization,

which are essential for assessing the performance of these devices. The iostat command generates

reports that can be used to change system configuration to better balance the input/output load

between physical disks1. This command is particularly useful for system administrators who need to

monitor and optimize disk performance and throughput2.
