SNMP trap configuration
« on: July 18, 2018, 10:40:54 pm »

Hi,

I'm trying to setup traps for BGP-sessions, and I've managed to get netxms to set alarm when they go up/down.
My problem is that I want the neighbor that went down to be in the alarm.

I can see the following in my SNMP traps log :

Trap OID: .1.3.6.1.2.1.15.7.2
Varbinds:
...;.1.3.6.1.2.1.15.3.1.14.8.8.8.8

The peer in this case 8.8.8.8 seems to be included in the Varbind/OID,
is there some way to extract this in netxms?
(I want to real-time output it.)

If extract is not possible, can varbinds be output unprocessed?

Regards

Currently it is only possible if you use "umatched trap" event. You can create event processing rule for that event and use the following script as action to generate new event with necessary data:

Code: [Select]
if (($event->parameters[1] == '.1.3.6.1.2.1.15.7.2') &&
    ($event->parameters[2] ~= "\\.1\\.3\\.6\\.1\\.2\\.1\\.15\\.3\\.1\\.14\\.([0-9]+\\.[0-9]+\\.[0-9]+\\.[0-9]+)"))
{
   PostEvent($node, "BGP_PEER_DOWN", null, $1);
}

This will generate event BGP_PEER_DOWN (you have to define it) with peer address passed as parameter 1 (you can access it in message text via %1).

Best regards,
Victor
