I use Orca (but then I'm its author:) ) to monitor Solaris and Linux boxes. I used it at Yahoo!/GeoCities to monitor 200 boxes and it was easy to see when systems were doing odd stuff.
Sample Solaris and Linux plots.
The Solaris version shows a whole ton of web server stats.
They have some monthly
and other
name server statistic plots available showing
the changes in traffic before and after the
upgrade.
These graphs were processed using Orca.
I like to use the bounds checking patches to gcc
to check code. You recompile your code and it
checks every array access, memory access, etc.
