Hi,
I followed the steps mentioned in the following website
(http://search.cpan.org/~hardaker/NetSNMP-TrapReceiver-5.0301/TrapReceiver.pm)
and configured snmptrapd.conf to register my perl module.
The module is called for every trap received but when the first trap
is received the formatting is not proper.
My conf:
snmptrapd.conf is edited with:
perl do "/usr/local/share/snmp/mytrapd.pl";
and mytrapd.pl contains:
############################
sub my_receiver {
print "********** PERL RECEIVED A NOTIFICATION:\n";
# print the PDU info (a hash reference)
print "PDU INFO:\n";
foreach my $k(keys(%{$_[0]})) {
$log->debug("$k\t$_[0]{$k}\n");
}
# print the variable bindings:
print "VARBINDS:\n";
foreach my $x (@{$_[1]}) {
$log->debug("$x->[0]\t$x->[2]\t$x->[1]\n");
}
}
NetSNMP::TrapReceiver::register("all", \&my_receiver) ||
warn "failed to register our perl trap handler\n";
print STDERR "Loaded the example perl snmptrapd handler\n";
############################
Output I got for the first time:
