Fwd: Nagios doesn't trigger command

I am very sorry but little correction:

Notification _is_ triggered (HOST_NOTIFICATION event in nagios3.log),
but command_line is not executed (probably).

command_line is very simple and I am pretty sure that run successfully.

So my question again: Is there any way how to see actual output of
executed command_line? Or at least to see some return code. Anything?

Hello dear Nagios users,
I am asking you in "emenergency case" because after 4 full days of
troubleshooting I am still not able to detect why Nagios 3 on Ubuntu
10.04 doesn't trigger commant upon hard DOWN state.

On Host State Information page I see that last notification has been
genereted before few minutes and number of total generated
notification is still increasing every check_interval.

But no command is executed! I tried to create replace default
notify-host-by-email's command_line to the very basic command 'echo
test > /home/libor/notif_works' to test if notification is triggered.

I enabled all debuging and in nagios.debug I can't find hostname or IP
of my host that is down.
