Nagios Support Forum

Hello,
I installed Nagtrap on Nagios and it seems to work fine.
But I have a problem with LinkUp Traps, I get a lot in a very short time for the same event.
Do you have an idea?
(sorry, Google translate)

thanks for your help

Just chiming in to say that I don't believe Nagtrap is maintained anymore.

Depending on your use case, you might use NSTI instead:

Thanks @mcapra for the tip.

It looks like Nagtrap uses snmptt to translate the Traps and the traps are logged in the following file. Take a look at that file for any clues on your issue or the system that sent them to see if they are logged there.

thank you for your quick reply

The snmptt.log file resembles the previous image, it receives on a very short time several LinkUp traps for the same host
The difference it finds in the message: A linkUp trap means that the SNMP entity, acting in an 18
In effect the value changes: 1,2,3,4,5 ...
For other traps no problem but only for LinkUP


Thanks mcapra I will learn about the tool nsti

If you do not need the linkup messages, you can remove them from the /etc/snmp/snmptt.conf file so the snmptt daemon will not translate them anymore.

Yes I think I will delete it, after all it is not necessarily useful
Thank you for your time
Last question about NSTI: Can it integrate on Nagios interfarce like Nagtrap or it necessarily uses a second interface? thank you

NSTI is it's own separate interface.
NSTI is a Nagios addon that makes managing SNMP traps easier. NSTI provide a PHP frontend for the SNMPTT database backend and allows you to filter SNMP results quickly and effectively to get a comprehensive overview of the information you want to see.

You can find more information about it here
