No NDO Utils at the moment. It's just a testing machine before leaving
Nagios 2 ;)

Load is relativ stable. Since I normally run 5 parallel instance I had a
load around 15 to 20 (4 CPUs).
I know it sounds like a big thing, but aslong the system doesn't begin
to swap or the I/O wait increases... i think it is not optimal but a
little bit away from beeing bad.

Process count might be interesting for that, I will add some general
process count monitoring tomorrow morning at work.
Thanks for the idea.

If you only want to see the nagios.cfg, there isn't any confidential
data in.

Out of my mind, my nagios.cfg diffs from the sample-config in:

- processing performance data (in that form that nagios only writes the
to a file which is rotatet by "mv" every 30 seconds)
- decrease of the different timeouts
- disabling ePN
- enabling large install tweaks
- since today: enabling rescheduling window
- ext cmd checking '-1' (this might be a little stressfactor)

I'll see if I can post my config tomorrow from office.
