It appears I had the wrong version of SNMP set in my monitoring system. When I changed it to v2c all interfaces were found properly. Now, I will have to wait to see if things are bring graphed properly. Thank you for the tip!

Hi Tim,

Yes, the rrdtool seems to work fine in the graphing, it generates
traffic graphs base on interface (but there is still a graph missing for
iflabel0 or something like this, not sure whether this is opennms or
pfsense problem). The OpenNMS seems to be able to identify it as the
source for Trapd, but I have not tested with any event generation.
However, OpenNMS can only assign a single "community string" to an IP
address (at least this is what I realized), this means that the
community string you set on your pfsense for both SNMP and Trapd must be
using the same community string.

About Router, I am not too sure what happened. I remember seeing OpenNMS
identifying a cisco equipment as "router" once before but it does not
recognized pfsense as "router".

I hope these help, I do not know to much about SNMP and still in the
process of exploring pfsense SNMP compatibility with varios open source
NMS, currently, OpenNMS seems to do the job best.

If it helps... May be we can talk more to see how can generate some
documents regarding pfsense and NMS.

Regards, Kelvin

When you say it doesn't recognize it as a router... in what regard? OpenNMS applies certain attributes to devices that it believes to be routers? Using OpenNMS are you able to poll individual interfaces on your box for graphing and logging purposes?

Hi Tim,

I do not know much to make any comments on what happened to the SNMP daemon on your pfsense. I am using OpenNMS and it seems to work fine, except that it does not recognize it as Router. I am using v2c for SNMP polling. I have not tested the trapd though.

Hello! I would like to monitor traffic totals with SNMP for each of my interfaces. I use JFFNMS as my network monitoring system. I enable

SNMP and set the proper community strings. However, when I poll the pfSense box, SNMP does not show the interfaces. Does pfSense use nonstandard OIDs? Also, does the SNMP daemon allow for per interface monitoring or does it simply provide an aggregate of traffic going through the system? Thank you!!!
