filesystem I/O measureware

[Marcia Ferreira_5]

Hi

How can I measureware filesystem I/O, using sar command? I can measureware this using glance (gpm), but I want to use sar because it will be use in a script.

Hi Marcia,

You can only measure IO per disk using sar/iostat. There are no 'per filesystem' stats available in sar.

You can script 'glance' to get the information.

Hi Marcia,

You cannot use sar to get filesystem sprcific stats. "sar -d" would give you isk stats only. You need to use glance and use the glance advisor to script and get the filesystem statistics that you need.

Hope this helps.

The closest you can do is sar -d, identify the disks associated with lvol (lvdisplay -v)

glance or gpm (x win) has a i/o by filesystem report.

There is a 60 day trail for the product on application cd's.
