Percent of Time RunQ Over the Limit, Per Day

Daily RunQ Graph.
The RunQ Over the Limit metric represents the percentage of time the run queue (i.e. number of
jobs waiting) is greater than 5 times the number of processors in the partition. The minimum value
for the number of processors is 5. For partial processor LPARs (less than one processor), 5 is
the value used for the number of processors.
The recommended threshold for RunQ Over the Limit is 20%. If the RunQ Over the Limit
percentage is consistently above this 20% guideline, then corrective action should be taken.
Corrective actions could include increasing the processor resource and memory resource
allocated to a partition.
