Survey of Nagios.

[Scott]

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"');
}
