Better than what?

Of course -- most of us are doing this.

You run the SE toolkit/orcallator.se on the target box that you want to
collect data on, and then you automate a download of that data file to the
machine that's running the orca program.  I use rsync, which is pretty
popular these days.

Keep in mind, though, that if you have a lot of machines, you're going to
want a pretty beefy server doing the graphing.  Orca runs as a single
process (although it'll gunzip your logs in parallel), so if that one orca
process has to rummage through a lot of logs, it could take a while.

We ran into this problem on a Sun E450 (4CPU).  We ended up taking an
extra Sun E250 and, using NFS, letting it do some of the work as well (we
have two locations, so this was an easy logical split for the data).
