Help with softflowd on pfsense

Post by fossicker » Mon Jan 30, 2017 11:10 am

I am a big fan of pfsense and am running it on my TimeWarner Cable Business Class Internet provision. No VLANs, with interfaces WAN (fxp0), LAN (em0) and Voice (dc0) on three separate NICs on the machine running pfsense. LAN and Voice networks are physically segregated and pfsense is the router and firewall for NAT'ing IPv4 and native IPv6.

I have softflowd configured on pfsense in the GUI, per ... _softflowd
I am interested in exporting flows from my WAN interface fxp0 so I have softflowd configured as recommended. I also have the snmpd package running and Scrutinizer is using the correct snmp community to poll pfsense. But Scrutinizer doesn't detect any interfaces at all (I am looking for WAN fxp0 to appear). I can get the default Report to run and I see meaningful results ostensibly on fxp0 since that's the only interface that softflowd is configured to watch. Can you help me get fxp0 to appear as an interface for my pfsense in Scrutinizer?
