Iostat avg-cpu
In the previous output, the CPU averages 50% idle waiting on IO requests to complete. Therefore, the amount of IOPS the disk can push becomes crucial. # iostat -x 1. avg-cpu: %user %nice %system %iowait %steal %idle. Usinf iostat command find which partition is used more and based on that we can drill down to which process is using that avg-cpu: %user %nice %system %iowait %steal %idle. This will produce 3 reports with 2 seconds interval: $ iostat -k 2 3. IOSTAT command in Linux: Syntax : iostat -x 10 > filename.

This command generates reports that can be used to change system configuration to better balance the input/output load between physical disks. The first report generated by the iostat command provides statistics The output of iostat is useful but its also nice if you can get it into a graph. The idea of this small repository is to show how this is done.
