Mark, thanks a lot for this explanation and the hints. I think I'll have a
look at the event broker thing.
C coding skills are required. For a nudge to get you started, have a look
at modules/helloworld.c in the nagios source distribution.
If you don't do it, I'll use this example as the module-writing exercise
for my Netways presentation. The first to complete it wins a weissbier in
the hotel bar :-)
Here's the completed thing. I rearranged things a tiny bit, so I had to
write it myself. How to compile is written in the top comment. You pass
it the script you want it to run as argument when loading it in the
nagios.cfg file. Make sure the script runs quickly, because Nagios
will be stalled while it's executing.
Note that on linux, you can achieve the same thing in a better way
using incrond. That won't work for other systems though, as inotify(7)
is a linux specific api.
