Utility to show which process ids (PIDs) are generating most I/O

L

LaR3

In Linux (>2.6.20) there is an utility called pidstat, which comes with sysstat >7.1.5. It is able to show which processes are generating most I/O requests on the disks.

Is there any tool that does the same thing on FreeBSD ? I've searched all the mans from pstat/iostat/systat a.s.o.

Thanks.
 
I'm struggling to remember but I've recently read Absolute FreeBSD 2nd Ed. and I think it says that when you're in the top utility if you press m it will show you what process(es) are using the disk bandwidth.
 
Code: 
top -m io -d 1
will give you the current count. Use -o for sort options (total read write fault vcsw ivcsw)

Code: 
top -m io
will give you the current status (not cumulative), with the o key plus keyword for sorting (total read write fault vcsw ivcsw)
