SNMP Trap not shown in SCOM-Console

Question

Hello!

I am using SCOM 2019 for receiving Traps from Network Devices.

I have installed it like https://kevinholman.com/2015/02/03/snmp-trap-monitoring-with-scom-2012-r2/

The Host receiving the traps is installed correctly

netstat -ano | findstr "162"  
  UDP    0.0.0.0:162            *:*                                    6400  
  UDP    [::]:162               *:*                                    6400  
  
  
tasklist /fi "PID eq 6400"  
  
Image Name                     PID Session Name        Session#    Mem Usage  
========================= ======== ================ =========== ============  
MonitoringHost.exe            6400 Services                   0    279 080 K  

SNMP Service is not running. --> should i deinstall it?

In Wireshark I see that the Traps are received.

But in SCOM console I don't see the Events.

I have read a lot of articles, but I don't know where the problem is.

Firewall is open

I have two server in the network resourcepool. on each server is running a discovery for network devices.

my problem is, that i sometimes receive traps.

Hi @Hansi ,

the cause could be that your resource pool contains two members. Are those 2x management servers both configured according to the article?
If not then this can explain why you sometimes receive traps and sometimes not.
Can you please try with only one server as Kevin suggests:

Next, I create a network monitoring resource pool in SCOM. I want to lock down which management server I will use to receive traps, and to lock this to a single management server for any troubleshooting.

How does it look then? Do you get them?

Answer 2

Hello
I am a little confused.

I have my "Network Monitoring Resource Pool" with two Members: SCOMSERVER1 and SCOMSERVER2
These Server I have have set up according to kevin's blog.

Now I have created a discovery-rule for my ups-devices running on SCOMSERVER1 and the "Network Monitoring Resource Pool"
I also have reated a second discovery-rule for my other devices on SCOMSERVER2 and the "Netzwork Monitoring Resourcd Pool"

if I have understood correctly the traps that are collected by rule should be sent to SCOMSERVER1 nd SCOMSERVER2, because only on of the Servers is the active Trap-Receiver.
But only a Server, that is a Target of Network Discovery, can receive TRAPS.

is this correct?
