to measure bandwidth used I use a script that checks the difference between bytes passed from poll A to poll B. I can point you to the plugin I use if you'd like. gives results like:
vr0:UP (131.0KBps/8.0KBps) and I get alarms in my email when I pass too much traffic like you'd expect: ***** Nagios ***** Notification Type: PROBLEM Service: Interface Status - vr0 Host: pipboy Address: 192.168.2.1 State: WARNING Date/Time: Tue Sept 29 08:02:33 EDT 2009 Additional Info: vr0:UP (WARN 1490.2KBps/56.2KBps) The OID it uses is just off the IF-MIB if I remember right. and most devices regardless of OS tend to respond to polls on the .1.3.6.1.2.1 trees, especially .1.3.6.1.2.1.2.2 and .1.3.6.1.2.1.25 , the first of which is the one you're looking for for interface information. 2009/9/29 Ståle Johnsen <stale.john...@smartit.no> > Hi, > I'm trying to monitor in / out bandwidth in bits on wan interface but are > having some problems finding the right SNMP oid. > > I found this one: http://cvstrac.pfsense.com/tktview?tn=257 but the OID > i'm trying doesn't return anything. > > Does anyone have any better suggestions for bandwidth monitoring on pfsense > from an nagios server? > > Regards > > Stale Johnsen >
