Hello again,
I realised my earlier perl script wasn't much use really, so I have modified
it to send an alarm to your WhatsUp machine syslog server if a number of
devices fail to respond to a ping.
Now what you need to do is modify a few lines in this file, run it via
scheduler or some such, and use WUG to monitor the syslog for the text it
produces.
(Configure / Events Library / Syslog, then set up an event to match on
something like "\w exceed maximum allowed")
I hope this is more useful ...
#!/bin/perl
use Net::Ping;
use Net::Syslog;
# Change the machines listed here to suit your setup. If the names cannot be
# resolved then it will count as a failed ping.
@machines = (s1,s2,s3,s4,s5,r32,r33,r34,r35,r36,r37);
# Initialise count of "down" machines to zero
$downcount = 0;
# Set "maxdowncount" to number of machines that need to be down to send WUG
an alarm.
$maxdowncount = 3;
# Set line below to your WUG syslog server's IP address
$sysloghost = "127.0.0.1";
# Loop through each machine in list, incrementing "downcount" for each that
doesn't respond to a ping
$p = Net::Ping->new("icmp");
foreach $host (@machines)
{
$downcount = $downcount + 1 unless $p->ping($host, 2);
}
$p->close();
# If number of device down equal or exceed downcount maximum then send alert
to syslog
if ($downcount >= $maxdowncount)
{
my $s=new
Net::Syslog(SyslogHost=>$sysloghost,Facility=>'user',Priority=>'debug');
$s->send('Aggregate down devices exceed maximum
allowed',Priority=>'alert');
}
exit;
