Nagios Support Forum

Hi There,

I have been struggling to find information on this. I've got a Linux box with three network cards in it. Nagios itself cannot access two of the network cards because it's on a different range, which is why I am trying to use SNMP to monitor the interfaces.
I have MRTG running and that works fine on my Linux box but I want to get this information into NagiosXI so that I can create alerts for it. I can't get it to display under performance graphs and I am not sure if I am going about it the correct way.

I tried creating an SNMP monitor using the wizard and putting OID's I found using the command "snmpwalk -On -v2c -c public 192.168.100.250 ifTable" There are many OIDs and I tried a few of them but all I could get was a status OK from Nagios with no performance graphs.

Can someone please assist me with this?

Tnx

Probably the easiest route, since you already have snmp enabled, try the switch and router wizard. It seems strange, but windows, linux, and network devices generally use the same oids for that information and we have had much success with it before. Additionally, it uses mrtg so if your other one is working already, this should be just the same!

I tried the Router/Switch wizard and it picked up the interfaces.

Many thanks for that!

I'm just waiting on the data to start collecting now so that I can check the Performance Graphs.

Awesome! I'll lock this up, and if you have issues let us know to reopen or create a new thread.
