Hi Stevie, thank you for answering!
Sure, so I read that there should be something extra, that handles the snmptraps, but I don’t know how to do it and what to use, because for me it looked like the old Icinga1 Instance had it working without all of this, but I might be wrong, I don’t have the correct information about that and don’t know what to look for, so I can’t compare it to the new Instance.
I installed some rpm packages that had to do with net-snmp (like utils etc.), but that’s about it.
There is something that I forgot to mention before: I send snmptrap heartbeats to the same destination hosts and those work perfectly, but those aren’t handled as notifications but rather as cronjobs.
Now to the important stuff, here are the requested informations and some more. The IPs, descriptions etc. are all dummies (security reasons) so if you see only a single letter or number don’t panic, I just wrote something else in the place of what is there:
notifications.conf

}

Used Icingaweb2 Modules
Only Monitoring is enabled
Also, is there a way to know, how I can check which program or service is used on the old instance for sendning snmptraps/mails notification? That would actually help a lot too.
Thanks in Advance.
Cheers,
Andy
