I have a server with 2 ethernet interfaces (eth0 & eth1) and a tunnel in my eth0. I'm trying to graph the traffic of those interfaces, but I only receive information of the tunnel. I tried with a local snmp application and with a remote application (PRTG).
First, with PRTG, I couldn't see the ethernet interfaces on the list, so I made a "service network restart" and then I could read those interfaces, but none of them show me information. The GREP tunnel does show traffic activity. Once I solved the problem restarting the server but I would like to know how to fix it without restarting the server.
I also restarted the snmp daemon, but it didn't fix the problem.
Any help will be apreciated.
