["Barr, Scott" <Scott_Barr@csgsystems.com>]

This redbook (old but still useful) has details on the trap flow:

I don't have time right this sec to post my recommendations for troubleshooting, but this book is a good place to start. In particular Chapter 5 (I think) has an automation overview with a good diagram of the daemon flows.

Subject: [nv-l] Need guidance in troubleshooting the reception of traps

I am looking for some guidance in troubleshooting the reception of traps on our Windows 2000 SP4 Netview 7.1.4 box. I am not sure at which point the trap gets lost.

 

I have a server that I am using to send the traps from, I have it pointed to both a lab and a production Netview Windows server. The traps work fine on the lab Netview, I see them in trapd.log every time. The production side is where my problems lie. I do not see any indication in trapd.log that the trap was ever received.

 

If, on the production Netview server, I restart the Windows SNMP Trap Service, and Netview, then send a trap I will see it in trapd.log. But within a short time any further traps I send do not show up. I do not know if the problem is with the Windows Trap service or in Netview.

 

What I am looking for is an overview of the flow the trap takes when it arrives at the server and how to troubleshoot each step to see where the failure is occurring.

 

Any assistance or pointers to troubleshooting documentation would be greatly appreciated.
