IOSTAT(1) Linux User's Manual IOSTAT(1) NAME top iostat - Report Central Processing Unit (CPU) statistics and input/output statistics for devices and partitions.  · The iostat command in Linux is used for monitoring system input/output statistics for devices and partitions. It monitors system input/output by observing the time the devices are active in relation to their average transfer rates. The iostat produce reports may be used to change the system configuration to raised balance the input/output between the physical disks. iostat is being included in.
