Hi
If someone know how to count %util value from iostat will be nice if
you share this informaction with me.
What I know ?
util=S_VALUE( ioj->ticks, ioi->tot_ticks, itv )
S_VALUE (ioj->ticks - ioi->tot_ticks / itv * 100)

and here is my problem, I don't know what is ioi->tot_ticks and from
where to taki it ?

tot_ticks - of ticks total (for this device ) for I/O

From where I will be know which disk will be counting ??
and from where i have to takie ticks for this device ??
/proc/diskstats /proc/stat ???

Thx
