Since I am fairly new to this responsibility, I would be interested in knowing what tools and/or methods
are being used to pass charges back to departments based on usage of  your HP3000.
 
In my current environment, almost all production work is done in the same account but with different user logons
for each department.
 
Disk space usage may be hard to divide up so maybe percentage of cpu usage would be the initial method.
 
Any advice would be appreciated
