{ Begin by giving some indication of load on the system during the day. 
  The best way to do this is to look at the average amount of idol time 
  on the system. This is just a general statement, it doesn't tell you if
  there was a period during the day where usage was very heavy. }

IF AVE[Idle Time] >= 85                THEN "SYSTEM LOAD VERY HEAVY"
IF AVE[Idle Time] >= 60 & AVE[Idle Time] < 85 THEN "SYSTEM LOAD HEAVY"
IF AVE[Idle Time] >= 35 & AVE[Idle Time] < 60 THEN "SYSTEM LOAD NORMAL"
IF AVE[Idle Time] < 35                 THEN "SYSTEM LOAD LIGHT"

IF AVE[Mutex & Misc Resource Wait] > 0.1 | MAX[Mutex & Misc Resource Wait] > 1 THEN "EXCESSIVE NUMBER OF PROCESSES IN MWAIT STATES"

{ Things should never get to be COMO. The menu system should leave half the
  user processes in HIB state, these are the first target for outswapping.
  Going beyond hibernating processes, the system should then attack LEF people 
  since there are a substantial number of users who log in and don't do 
  anything. }

IF MAX[Compute (Outswapped)] > 0 THEN "SOME PROCESSES WENT COMO."
IF AVE[COMPUTE] > 1 THEN "SUBSTANTIAL NUMBER OF PROCESSES WAITING FOR CPU"

{ Part 2 - Look at system memory utilization }

{ inswap rate of 0.1 on vax 750 (source: Digital Review 2/6/89 pg. 31)}

{ Part 3 - Look at the disk system }
