create SLA (Service Level Agreement) and help out queuing jobs into the queue

Since I don't see you mentioning it, I'd suggest you start by googling for 
ganglia and Beowulf. You'll hit quite a few live Beowulf clusters being 
monitored using ganglia. Visit a few of these since ganglia is customizable 
and different metrics of interest could show up. This should at least get rid 
of the "blank page" phenomenon. Then would follow the 1001 journals articles 
in ieeeXplore concerning computer metrics in an HPC environment ;)

Some kinks ;)
http://ganglia.sourceforge.net/ (click on the live demos...but google will 
give you lots more)

Ganglia is nice for a quick, coarse/medium grained overview of your system. 
Non-intrusice, fine grained monitoring might require more sophisticated 
equipment (network packet analyser for net performance comes to mind...)

rgb's wip has a chapter on metrics and tools to measure them as well as what 
to watch out for...
