creating custom mib

Hi guys,

Maybe this is not the place to ask with help for creating a custom MIB and if not then if someone could point me towards a forum or mailing list I'd be very grateful.

I have a lot of scripts to monitor various systems and most of them will have some sort of built-in alert functionality that will send an e-mail.. it's a bit messy to have that functionality all distributed and I wanted to see if snmp traps may be a better way to go. We cover all the monitoring functionality with polling for reliability but snmp-traps we use to speed up alerting for critical systems.

To learn more about this I want to create my own MIB and I have an enterprise OID (1513) that I can use.

So I send traps with SNMPv2-SMI::enterprises.1513.... and passing along some variable and this is where I'm struggling with syntax and general lack of understanding. I want to format my mib in the correct way.. maybe it should be split down into one mib defining objects and then I define the notifications in another mib.. and and.. so many questions :) I can see various examples out there but I'd love to have a conversation with someone who actually knows this stuff.


This is what I have so far:


Advania-Traps-MIB DEFINITIONS ::= BEGIN

IMPORTS
   enterprises                                  FROM RFC1155-SMI

advania                                OBJECT IDENTIFIER ::= { enterprises 1513 }
objects                 OBJECT IDENTIFIER ::= { advania 1 }
notifications       OBJECT IDENTIFIER ::= { advania 2 }

-- Objects

trapState OBJECT-TYPE
    SYNTAX      DisplayString (SIZE (0..31))
    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
            "A brief description."
    ::= { msg 1 }

shortMsg OBJECT-TYPE
    SYNTAX      DisplayString (SIZE (0..31))
    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
            "A brief description."
    ::= { msg 1 }

longMsg OBJECT-TYPE
    SYNTAX      DisplayString (SIZE (0..1279))
    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
            "Detailed info."
    ::= { msg 2 }


-- Notifications

customTrap NOTIFICATION-TYPE
       STATUS current
       VARIABLES { trapState, shortMsg, longMsg }
       DESCRIPTION "Custom trap alert."
       ::= { notifications 1 }

END

Not sure if this is how it's meant to be formatted, any help would be appreciated..
