Inspect is a new monitoring tool included in Sun Grid Engine (SGE) Update 3. It is a flexible interface for viewing current and historical data about SGE cluster(s) and the Service Domain Manager. The new GUI-based monitoring tool is developed purely in Java and uses JMX. This means an SGE installation has to enable JMX. Users interested in using Inspect must have version 6+ of the following software: Sun JDK, OpenJDK, IcedTea, and Apple JDK.

The Image Packaging System (IPS) in OpenSolaris 2008.05 comes with a graphical user interface known as the Package Manager that features install/remove packages, package repository search, package information, and more.

“AFAIK IPS does not do locking (yet). So running multiple UIs at the same time can produce unpredictable results. See bug: http://defect.opensolaris.org/bz/show_bug.cgi?id=1668”

Saha offers an image example of the GUI and links for more on the IPS on his weblog.
