EUREEKA!!!
Thanks to some other users for pointing this out and helping me
resolve...
Somehow when I converted config files from Nagios 1.x to 2.9, my
timeperiods.cfg was messed up and had the 24x7 entry going from
0:00-0:00 everyday, when it should have been 0:00-24:00 everyday. This
caused all my checks to be scheduled at midnight everyday.
Thanks for all the help with debugging flags and config files.

Klaus

Subject: Re: [Nagios-users] Debugging Nagios?

nagios.log and syslog were of no value, but I was able to build with
debug (./configure --enable-DEBUGALL) and see where Nagios is forcing
all checks to occur at midnight tomorrow.
I've seen several posts on this with questions, but no answers. Does
anyone know how to fix the scheduling in Nagios so it does not schedule
all checks at midnight every day?

output below is from running 'bin/nagios -s etc/nagios.cfg' with debug
on.
Notice that all checks are scheduled for midnight tomorrow.

What a great question! Well there's nagios.log in /var/spool/nagios,



use_syslog=1


log_event_handlers=1
log_initial_states=1
log_external_commands=1
log_passive_checks=1
log_notifications=1
log_service_retries=1

But getting debug out the schedule probably requires a debug build of
the binary.  

~~BAS

PS It could be worse, you could be trying to debug a plugin/module.
