Subject: Re: [Nagios-users] Survey of Nagios.

This is OK I presume, 

But how should I take care of nagios notification, if I set  a service into nagios, and like to notify persons in charge of this service ? 
Into the script we just checks the nagios running state. 
Any idea ?

Just to make an appendment to this, I noticed I had it in a test state

while writing it... here is the actual working copy.. sorry about that

folks.. enjoy



#!/usr/bin/perl



open PIDFILE, ("/path/to/nagios/var/nagios.lock");

$pid = <PIDFILE>;

close PIDFILE;

@nag_stat = `ps -ax |grep -e $pid`;



if (@nag_stat[0]) {

        print "nagios running\n";

} else {

        system('printf "Nagios not running: replace this with external

command\n"');

}
