[TriLUG] Other ways to get to iostat data?

[ablum gmail]

You might be able to get what you need from vmstat provided by the
procps package (which you have if you can run the ps command).  If you
run vmstat with -d flag it gives useful disk stats like:

# vmstat -d 1 300

disk- ------------reads------------ ------------writes-----------
-----IO------
       total merged sectors      ms  total merged sectors      ms    cur
