I would like to build a custom MIB in which I define some useful objects that can be accessed and managed by others (clients).. I've been googling this for hours now without finding any interesting documentation about that..

So first of all, is is possible to build custom MIB? if yes, is there any interesting web sites to deal with this issue? would be really grateful if you answer me, so that I can switch to other solutions if SNMP4j is not appropriate for my application..

Cheers,

Marie

If you are looking for a toolset to create a SNMP agent (command responder) with SNMP4J(-Agent) then why not using AGENT++ MIB Designer to define the MIB specification and then AgenPro to simulate the agent (based on SNMP4J-Agent) and generate the stub code for SNMP4J-Agent.

You will get a running (although no yet instrumented) agent within a few minutes without the risk of making errors while transferring the MIB design to the agent code.

With the simulation agent you may try the MIB design before you generate the code.

There are multiple ways to build code responding on 'your own MIB'.

First of all the vocabulary (it will help to google): the deamon (or service) waiting on an SNMP port (161) is called Agent. If I understand you want that this agent gives responses on new MIBs (yours). For this you need to create a Proxy Agent for you agent.

Solutions : Proxy Agents are not so standard.

  1. If you are able to rebuild your agent (Net-SNMP) you can build in the code for your MIB. The kind of agent you can rebuild provide compilers that create skeltons code from MIB file. After that you can choose to load your code into the agent or in a separated module. See TUT:Writing a MIB Module.You can find something similary for Microsoft integrated SNMP agent (even if you can't rebuild the agent). It exists much commercial SNMP solutions that allows to build your own Agent.
  2. It exist a standard to extend Agent which is called AgentX (it's not talking about spy)

Now I let you googling with build an agent with SNMP4j or build a proxy agent with SNMP4j. As I can read "The SNMP4J-Agent pure Java SNMP agent API adds command responder including notification originator and proxy forwarder support to the SNMP4J core API" it sound promising.

  • Your answer is focused on building an agent rather than developing a custom MIB as requested by the questioner. Is there any tool which helps me build my MIB? – pavanlimo Nov 08 '11 at 07:03

    Yes, you can use [MG-SOFT Visual MIB Builder for Windows](http://www.mg-soft.si/builder.html?p1=products&p2=mgProductsNMA-SMI) – JPBlanc Nov 08 '11 at 11:10
