Description Manuel Amador (Rudd-O) 2007-07-15 04:28:19 UTC

Version:           1.2.0 (using KDE 3.5.6, Kubuntu (feisty) 4:3.5.6-0ubuntu14)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.20-16-generic

For each block volume, in addition to requests per second and blocks per second, it'd be HELLISHLY useful to have a sensor measuring disk request depth.  For many of us, the limiting factor and the responsiveness killer is busy disks rather than high CPU usage, and this sensor would be of unmeasurable help in letting us find out when the disk is busy.

Fixed in 4.0.
Also note that 4.0 has support for cpu i/o wait

Fantastic, thanks :-)  You win fifteen thousand internets!
