I wonder how I can monitor which process takes out all my I/O bandwith. The only command I know is gstat
but it shows cumulative info. Are there any tools I can use to inspect the running processes for their I/O usage? The system is FreeBSD 8.3.
By using iotop command, you can monitor the disk utilization by individual processes. You will get the following output: By typing the iotop command with o option, you will get the actual I/O activity. With the help of iostat command, you will get the individual hard disk I/O activity.
The answer is to use top
then hit m to display IO percentage per process/thread.
