Use iostat to display informations about CPU statistics, input/output statistics for devices, partitions and network filesystems (NFS).
The basic syntax for the iostat command is:
iostat [delay [count]]
- The delay between updates in seconds. If no delay is specified, only one report is printed with the average values since boot.
- Number of iterations. If no count is specified and delay is specified on command line, count defaults to infinity.
|Reports from iostat||Command|
|Report CPU statistics (one iteration):||
|Report disk statistics every 1 second, 10 iterations||
|Report extended disk statistics||
|Report disk statistics for /dev/sda1 partition||
|Report network filesystem (NFS) statistics||
