Job Queues 

The job queue monitor checks the average number of processes that have been waiting for CPU and performing disk I/O over the last 1, 5, or 15 minutes. A value of 4 in /system/jobQueue5Min means that at the time of polling there was an average of 4 jobs in the queue over the last 5 minutes.

The MIB variables computerSystemAvgJobs1, computerSystemAvgJobs5, and computerSystemAvgJobs15 from the hp-unix MIB provides the resource value to the monitor.

To verify the load averages on the system, use the uptime (1) command.

Table 7-3 Interpreting Job Queues

Resource Name

Value Range

Interpretation

/system/jobQueue1Min

integer

average number of jobs in the queue in the last minute

/system/jobQueue5Min

integer

average number of jobs in the queue in the last 5 minutes

/system/jobQueue15Min

integer

average number of jobs in the queue in the last 15 minutes

 

The minimum polling interval is 30 seconds. Unless your system load tends to fluctuate wildly and need load-balancing attention frequently, set a polling interval greater than or equal to the job queue interval: 1, 5, and 15 minutes, respectively.
