Or you can try wulfware (xmlsysd and e.g. wulfstat or wulflogger).
Depends on what you want to do with the data.  wulflogger makes it very
easy to log a variety of cluster load metrics into a file at a selected
interval, in case you want to actually run programs to analyze it or
plot it with standalone tools.

It should be prebuilt for FC2, RH9 and Centos 3.3 here:

(or available in source rpm or tarball if you prefer).  I've tried to
make this a yummified repository, so you can if you wish autoupdate from
it via yum, or of course you can just grab source or binary rpms and put
them into a local repository.
