Hi All, I have a Dell PowerConnect sending sFlow data to PRTG. I'm trying to define a sensor for total traffic in/out (of two switch ports connected to the "outside"), but those channels are not listed as an option in the Channels configuration of the sensor.

I added the sensor using the std. sFlow type. I'm assuming that "template" only contains specific channels and for what I'm trying to do I need to use the sFlow (Custom) template. (that's a question, not a statement ;) ).

The other question is, what would be the channel definition for "Total-In" and "Total-Out" ?

Thx in advance! Marcus.

Hello,

to get these channels, you would basically need to use a Custom Sflow-Sensor and define the Channels the way that traffic between internal IPs is disregarded (Exclude Filter), and then two channels where internal IPs as sources, and everything else as destination is "Traffic Out" and the other way around is Traffic In, for details on Custom Flow Sensors and Filters please see: Frequent Questions about Flow (NetFlow, sFlow), Packet Sniffing, Traffic Monitoring and Cisco.

best regards.

Hi Torsten, thx for the quick reply. As I stated this is for monitoring "outside" traffic (Internet). Based on the information in the link you posted, could you comment on this:

#1:Traffic-In
DestinationIP[a.b.c.d/240] or DestinationIP[w.x.y.z/224]
#2:Traffic-Out
SourceIP[a.b.c.d/240] or SourceIP[w.x.y.z/224]

Will this work (correct syntax)? Do I need to also specify the destination on both channels as you mentioned in your post?

Thx again and viele Grüße aus SoCal ! Marcus.

Addendum: sorry, the mask in the CIDR should contain bits of course, not the octet in decimal ...
