If service fails, check ping before sending a notification

[Dean Bishop]

Hmmm.  This is how Nagios works.  If a service goes from an OK state to a
Non-OK state it immediately runs the check for the host (as defined in
hosts.cfg).  If the host check (commonly check-host-alive which is a ping
check) returns an OK state, then the service in question is scheduled for a
recheck at its defined retry interval.  If the service is still in a Non-OK
state after the service's defined max_check_attempts then notifications are
sent.

If the host check returns a Non-OK state, then the host check command is run
at the highest priority (i.e. immediately and without interruption,
interrupting normal scheduling).  If, after the host's defined
max_check_attempts, the host is still in a Non-OK state, then notifications
for the host are sent and all services running on this host are rescheduled
at their normal check interval but notifications for these services are
suppressed.

In other words, what you are describing is not the way Nagios works.

How do have your services dependant on ping?
Do the services have the unknown notification_option enabled?  This
shouldn't matter but maybe it does.

A snippet from the configs and more info regarding the notifications would
help.

Later,

Subject: [Nagios-users] If service fails, check ping before sending a

Is it possible to do this:
If a service fails, check if we can ping the host before sending a 
notification about every service.

The reason is that one of our servers were unreachable this night, and we 
all got a message for every service about this.

I know that I can set every service to be dependant on ping, but what if 
Nagios checks 4 services that fails before it discovers that ping has also 
failed?
