Feeling a bit 'trapped' by Net::SNMP

[Ian Zapczynski]

Hello all,

I hope my question isn't too specific for this list. I'm still learning the basic concepts of SNMP, but I need my current script to send an SNMP trap to a host here upon failure. I am hoping to use Net::SNMP to do so, but I think I'm unclear of the syntax due to my current lack of understanding of the SNMP protocol.

I have a subroutine which looks like this:

sub sendSNMP {
my ($event) = @_;
my ($session, $error) = Net::SNMP->session(
hostname => $SNMP_HOST,
version => "2",
timeout => $SNMP_TIMEOUT
);
die "SNMP session to $SNMP_HOST failed - $error" unless $session;
my (@oid_value) = ( ".1.3.6.1.4.1.1000.3.$SNMP_SERVERID.$SNMP_JOBID.0.$event",'INTEGER','');
my $result = $session->snmpv2_trap(
-varbindlist => \@oid_value,
);
my $error_message = $session->error;
die "SNMP trap could not be sent to $SNMP_HOST because $error_message" unless defined ($result);
$session->close;
}

I'm quite sure my problem is in not understanding what -varbindlist is supposed to be populated with. I took the above from an example I saw on the 'net which I probably misinterpreted.

I am really trying to translate a command line used by snmpnotify to communicate with HP Openview to a function using the Net::SNMP module. The only thing I know I must specify is a complete OID as constructed above. But can anyone else tell me exactly what is supposed to be in -varbindlist? The perldoc specifies:

sysUpTime.0 - ('1.3.6.1.2.1.1.3.0', TIMETICKS, $timeticks)

snmpTrapOID.0 - ('1.3.6.1.6.3.1.1.4.1.0', OBJECT_IDENTIFIER, $oid)

I don't understand though if this is meant to be literal or just examples.
When I run the script with the syntax above or the other attempts I've made, $error_message contains "Unknown ASN.1 type [INTEGER]"

A pointer to an RFC would even be appreciated. For some reason, I can't seem to find one which explains what I'm looking for.

Thanks for any and all insight!
