iostat & DISK bps

[Nikee Reddy]

Hello,

In our system we have around 60 disks presented. when I run the iostat command I see all the disk IO details including of those disks with '0' IO.

Is there any way for me to find only those disks which has an IO value morethan '0'?

Thanks,
Nikee

Hi,

use

iostat|awk '$2!="0"{print $0}'

I Think that sar is more accurate than iostat.

try "sar -d "

you will get data for every disk device file, only if it did I/O. You also get an average at the end (after "count" iterations).

Good Luck,
