Mon::SNMP(3) decode SNMP trap

SYNOPSIS


use Mon::SNMP;
$trap = new Mon::SNMP;
$trap->buffer($snmptrap);
%traphash = $trap->decode;
$error = $trap->error;

DESCRIPTION

Mon::SNMP provides methods to decode SNMP trap PDUs. It is based on Graham Barr's Convert::BER module, and its purpose is to provide SNMP trap handling to ``mon''.

It is not complete, so don't bother trying to use it unless you are ready to debug and write some code.

METHODS

new
creates a new Mon::SNMP object.
buffer ( buffer )
Assigns a raw SNMP trap message to the object.
decode
Decodes a SNMP trap message, and returns a hash of the variable assignments for the SNMP header and trap protocol data unit of the associated message. The hash consists of the following members: 

        version         =>      SNMP version (1)
        community       =>      community string
        ent_OID         =>      enterprise OID of originating agent
        agentaddr       =>      IP address of originating agent
        generic_trap    =>      /COLDSTART|WARMSTART|LINKDOWN|LINKUP|AUTHFAIL|EGPNEIGHBORLOSS|ENTERPRISESPECIFIC/
        specific_trap   =>      specific trap type (integer)
        timeticks       =>      timeticks (integer)
        varbindlist     =>      { oid1 => value, oid2 => value, ... }

ERRORS

All methods return a hash with no elements upon errors which they detect, and the detail of the error is available from the

EXAMPLES

    use Mon::SNMP;
    $trap = new Mon::SNMP;
    $trap->buffer($snmptrap);
    %traphash = $trap->decode;
    foreach $oid (keys $traphash{"varbindlist"}) {
        $val = $traphash{"varbindlist"}{$oid};
        print "oid($oid) = val($val)\n";
    }

ENVIRONMENT

None.

NOTES

CAVEATS

Mon::SNMP depends upon Convert::BER to do the real work.
