=head1 DESCRIPTION

This output type will send a SNMP inform request for each converted input.  See L<Net::SNMP> for a list of the ConnOpts section parameters.

=head1 OUTPUT FORMAT

Output templates should use the following format:

    1.3.6.1.2.#.#.#.#  #  Value, blah blah blah...
    1.3.6.1.2.#.#.#.#  #  Value, blah blah blah...

In other words, each line is a set of varbinds.  Within each line is a set of 3 values, separated by whitespace:

=over

=item *

OID

=item *

Object Type (numeric form)

=item *

Value

=back

A list of object types can be found L<here|https://metacpan.org/source/Net::SNMP::Message#L75>.

Please note that SNMPv2 defines the first two variables bindings as such:

     # sysUpTime.0   TIMETICKS          $timeticks
     # snmpTrapOID.0 OBJECT_IDENTIFIER  $oid
     1.3.6.1.2.1.1.3.0       43  ....
     1.3.6.1.6.3.1.1.4.1.0    6  ....

Make sure these are included in your template.

=head1 TODO

Use L<Net::SNMPu>, when that gets released...
