[Beowulf] Performance metrics & reporting

[Matt Lawrence]

What do folks recommend for gathering and reporting performance data on 
Linux (CentOS 5) systems?

Since I have done a lot of this on AIX, my initial thought is to use the 
Linux version of nmon and nmon2rrd or nmon2web to generate web pages of 
performance graphs.  Since I already know the tools, wrapping it up in 
scripts to run automatically would be really easy.

My goal is to make it really easy to provide useful information to users 
without them having to constantly ask me.

Thoughts?
