You're welcome to try xmlsysd/wulfstat or xmlsysd/wulflogger.  They are
available via links here:

  http://www.phy.duke.edu/~rgb/Beowulf/beowulf.php

and are fully open source/GPL tools.  Probably the best toplevel page is
here:

  http://www.phy.duke.edu/~rgb/Beowulf/wulfware.php

and there is a very low traffic mailing list if you want to join.  I
tend to support it fairly aggressively -- there are bugs, I suppose, but
we use the tool here and I try to resolve the bugs quickly.

Various views permit you to track in considerable detail the resource
consumption of each significant task on each cluster node, and it is
easy to set up to view a cluster with xml-based configuration files.
