If you can use Solaris 10 DTrace, you can use the $SGE_ROOT/dtrace/monitor.sh script to monitor a Grid Engine master and look for any bottlenecks. The monitor.sh script supports the following options:
Specify statistics interval to use. The default is 15sec. A larger interval results in coarser statistics, while a smaller value provides more refined results. Most useful values range from 1sec to 24hours.
Required if $SGE_CELL is not “default.”
Display qmaster spooling probes in addition to statistics. This option enables you to view more specific information about a presumed spooling bottleneck.
Shows incoming qmaster request probes. This option enables you to view more specific information to evaluate instances in which someone is flooding your qmaster.
Any critical, error, or warning messages appear in monitor.sh output.
