This directory contains a program, BUSUSE, written at the Washington University
School of Medicine to measure the disk IO load on your VAX.
It is a direct decendant of an earlier program called MBAUSE.  It generates
a monitor like display of the activity on each disk drive and on each MASSbus
adapter.  Included in the display are the instantaneous QIO rates to each
drive, a long term average of each drive QIO rate, the percentage of time
each drive is busy, the average length of each drive wait queue, the average
length of each drive's ACP queue, the percentage of time each MBA is busy,
and the average channel wait queue length for each MBA.

A command file is included to build the program.  Since BUSUSE has its
fingers in the executive, it will have to be rebuilt for version 4 of VMS.
In fact, if you don't rebuild BUSUSE each time you move to a new major
release of VMS, then it will probably crash your system.
