Just a couple of suggestions that may help you.

I would put the IP address into an array. The loop through and look for the agent_address:

i.e.

@ips = qw(10.216.74.137 10.216.74.144 10.216.74.148);
$agent_address = "10.216.74.144";
foreach(@ips) {
print "$_\n" if(/$agent_address/);
}

And for the second one, maybe using a search\replace regex to grab the end of the string:

i.e.


$probablecause = "enterprises.alcatel.nmu.genos.alarmHandoff.alarmHandoffObjects.alarmTable.alarmEntry.probableCause. 3 200904 = Replaceable Unit Missing";
$probablecause =~ s/.*probableCause.*\s=\s(.*)/$1/;
print "$probablecause\n";

Hope this helps.
