I believe you can configure the agent on that server as a proxy to receive those SNMP traps and then configure the application to send them locally (to 127.0.0.1 or ‘localhost’). The local agent will then pick them up and react to them just like any other rules or monitors would have. The SNMP traffic would never actually leave the server and thus no firewall rule would be necessary.

Check this link for more information about how to set up an SNMP receiver:

I have never done this, so I could be way off base here, but at least it’s a start. Report back here on your success or failure and we’ll continue to work on it if needed.

Hi Aaron,

When you use two management systems (like SCOM and some other tool like HP Openview) these are independet systems. Both manage the same device. For polling there shouldn’t be any problem (as long as you use SNMP v1 and v2 and know the community string) and if you need the traps on both systems you need to forward it to SCOM from a 3rd party tool or from your other management system.

SCOM 2007 cannot forward SNMP traps to other systems out-of-the-box. In MOM 2005 this was possible but this is one of the features MS cut from SCOM. You need to look at some 3rd party tools or maybe your other management system is able to forward received traps to SCOM.

To be honest, the SNMP story in SCOM is not a good one. There are a lot of issues implementing it and it’s not very easy to set up properly.

cheers,

Stefan

Thanks Stefan!

What do I need to know to set this up? I am guessing there is some settings on the Microsoft SNMP manager I will need to mirror on my building automation system or are the two system really independent. I have been reading into it and seems there is something called “community strings”.

Thanks

Aaron

Hi Aaron,

there are basically two parts involved in SNMP monitoring:

1.) polling values from SNMP devices (like CPU, bandwidth, etc.)

2.) receiving traps (events when something goes wrong)

Polling the values will work from multiple SNMP management systems but for SNMP traps, it depends on the device if it is possible to setup more than one trap receiver. There are also trap forwarders allowing you to receive a single trap and distribute them to multiple systems. In fact some SNMP managers can receive traps and at the same time forward it to another system.

Hope this helps.

cheers,

Stefan
