Nagios Support Forum

Hello everyone,

If one device is in a different network range from Nagios XI (device is 192.168.3.10 and Nagios XI is 192.168.5.10), by connecting that device to Nagios XI using SNMP, will Nagios XI be able to automatically detect that device or there has to be some further configuration?

Thank you!

I can't answer on the automatic detection, but you want the ports open for SNMP between hosts. You can check between nagioshost and snmphost with nmap, sending test traps from snmphost, and snmpwalk to snmphost as well.

nagioshost% nmap -p 161 snmphost
snmphost% nmap -p 162 nagioshost

I may have gotten the trap and listen ports backward--I always forget...

In theory perhaps, in a company with multiple networks, there might be a way

to connect all of them on Nagios just by connecting router to all of those networks,

from where router itself can send packets between those same networks.

Because they have to be connected physically somehow in order for them to be visible to Nagios.


If there are some alternatives, I am happy to hear.
