Thanks for reaching out @vretic,

Could you provide some more details about the issue you are describing? Which version of XI do you have? Which distro are you installed on? Are there any errors in the PHP/Apache logs?

Review the Nagios XI log files (typically located in /var/log/nagios/) for any errors related to trap processing. This may provide insight into whether the traps are being received but not displayed. papa's games

What is in the status of the trap service for the host? The trap says the state is normal so the trap service should be green and say something about a warmstart.

Hi,

that is the strange thing.
If I compare it with other hosts (hosts that were allready in the system before the upgrade to 2024R1.1.5) the service was stuck on pending when I created it. I forced an immediate check which made the service turn green. Than there was no next check date so I reconfigured the service and created a check interval of 1min.
So the current status of the service is OK:Trap reset

Hi,

I'm running nagios 2024R1.1.5 installed on RHEL8.
I checked the /usr/shared/nagiosxi/var/event_handler.log and found the following error, not sure if its related.

Check under admin unconfigured objects since the trap isn't getting attached to the host. You may also want to see if the IP resolves to the hostname.

Hi,

checked it and yes the service was in the unconfigured list, reconfigured it, now its gone from the unconfigured list but still no notification and I still get the same error in event_handler.log....

Time to generate a trap ans start from the beginning.
Another question is the trap service the same as the ones that are working?

Hey,

yes the trap service is the same, I'm using the wizard....
I figured it out, I configured the host with host name ex. ups_locna.....
In the snmptt.log I can see the line received trap from ups_locna...
But in nagios.log there a corresponding line but with an ip address and off corse host not found as the host address is the hostname.
Is there a file where I have to bind hostname with ip address?
I did it in /etc/hosts with no difference.
