usage accounting

[Fred Velijanian]

I'd like to charge users less who run their processes at a lower priority 
(i.e. nice'd). Unfortunately I cannot find any applicable fields
stored in the system accounting file. (structure defined in <sys/acct.h>)
Is it possible to tag each process such that this information can be 
recorded in the accounting file? Running a special program which sets the 
"nice" priority and then execs the user's command is also acceptable, however
all processes created by the user's command need to be considered as well.

Os used: Sequent DYNIX V3.0.12.

Has anyone encountered this type of problem, any solutions?

Thanks in advance,
