currently the best you can get from collectd directly is the
`collection3' script included in the contrib/ directory. The layout
itself doesn't look very good, but it's very functional and most graphs
are pretty.

There's been some discussion about using Cacti just recently, you can
find the conversation in the archives[0].

Then there's YaketyStats[1]. They have a nice frontend and I tried to
use that with RRD files created by collectd, unfortunately it's not that
easy: They require certain DS names and only use the MAX CF (a huge
design-bug in my opinion, although apparently they did that on purpose).

Yes, there are RRDtool packages for RHEL somewhere, but I don't know
exactly where to get them. Dag Wieer's RPM repository comes to mind,
though ;)

RRDtool 1.3 has some nasty dependencies, there's hardly anything you can
do about that. You might want to consider using RRDtool 1.2, though. It
uses another graphing backend which is much easier to please..

Hope that helps..? Regards,
