Sun N1 Grid Engine 6.1 Administration Guide

Tuning Performance from the Command Line through DTrace

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:

-interval value

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.

-cell cell-name

Required if $SGE_CELL is not “default.”

-spooling

Display qmaster spooling probes in addition to statistics. This option enables you to view more specific information about a presumed spooling bottleneck.

-requests

Shows incoming qmaster request probes. This option enables you to view more specific information to evaluate instances in which someone is flooding your qmaster.


Note –

Any critical, error, or warning messages appear in monitor.sh output.
