Monitoring System Resources
System Monitor Reference
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 5-2 Interpreting Job Queues
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.
