Nagios Support Forum

Hi,
I did an interface trap test by bringing down eth4 of a server. I am receiving the snap traps and I also see nagios receiving passive check result but it could not find the service. When I bring the eth4 up, I see the traps received and I also see nagios able to find the network interface up service.

Logs of eth4 down-

I have defined my passive services for both interface up and down-

define service {
use pcmm-passive-base
service_description Network Interface Down
}

define service {
use pcmm-passive-base
service_description Network Interface Up
}

and I also have the snmptt.conf file having the traps with OID for both interface up and interface down.

Please help what am I missing? Why is nagios not detecting network interface down service?

You will need to configure your services properly to display and hook in with those traps, have you taken a look at a guide such as this one?:
