Hi,
I like it when people periodically post numbers and architecture
summaries, I am guessing with the distributed frameworks out now for
Nagios this thread might be seeing bigger numbers than past threads
have.

Nothing bad about using a VM, they just fall over horribly (generally

+1 for Thruk + multi-site - well done project, easy to set up and easy
to replicate a set up across multiple hosts.
I haven't tried it with a large Nagios installation.
Query capabilities are very cool as well.

What minor RHEL rev are you running? We had one poller that was

to do that? Setting up an explicit serviceescalation for

Max Schubert is working on a patch that does something similar to that.
If he doesn't complete it, I might take a look at adding it myself.

Please respond to the list with the version of Nagios you are using

hello,
Definitely check out Merlin - through configuration you can have Nagios
instances communicate events with each other using a few types of
relationships and you can then serialize the data from an instance to a
database for either using their custom UI or making one of your own.
There is a debug level you can set in nagios.cfg that will show you
all commands being executed - an easier way would be to make a shell
wrapper for check_int that logs all args and then execs them with the
real check_int. Something like
