Re: [Nagios-users] How to surpess notifications if ping fails.
For some reason notifications are not being sent from nagios when i unplug
the network cable from one of the hosts being monitored.
Nagios recognizes that the hose is down but no notification...

Here is the host config...

usegeneric-host
check_command check_alive
notification_optionsd,r
max_check_attempts 3

}
Any thoughts to why this isn't working? Email notifications for other
services is working fine. Maybe i need to add check_alive as a service?

Yep, that'd be a nagios 3 option. I'd not realized (or maybe
missed) you were using v2. Just remove that option.

Its up to you how you want to format. Sometimes it's easier to

Here, nagios is running the 'host-notify-by-email' command for the
contact named 'root'. It's trying to send a notification. Does that
command_line work as the nagios user from the command line? Do you see
any indication of the attempt in your mail server log files on the
nagios machine?
If it's not obvious what the problem is, please post that command{}
definition, the contact{} definition for root and your test from the
command line as well as any errors seen.

Yes, that's one way to do it, though over-complicating it. The other
is to actually have ping (usually defined as check-host-alive) as the
host check, when the host is unreachable, the notifications for the
services will not be sent.
Nagios3 would also be a good idea for an upgrade (something I believe
ubuntu has as a package already) as the host checks are much better in
v3.
