add http Channels of packet Sniffer for differnet Devices

In case you're referring to this Packet Sniffer Sensor, this one is only capable of monitoring traffic passing through the local network interface of the PRTG Server or of a Remote Probe. In case you meant something else, please let us know.

Kind regards.

hi I mean something else, I install Remote probe on some of computers in my local network and in server used packet sniffer. I want to know if it is possible to see total traffic of http channel of packet sniffer for some of my devices(here is computers) for example from range of 172.20.20.1 to 172.20.20.10.now only I can see live graph and detail for every individual computer I want to see a live graph of total traffic for a custom range of devices.(sum of http traffic in every device)

Ok, so we have a few Remote Probes, each one running a Packet Sniffer and you want to consolidate data for HTTP traffic from those into one sensor. You can do this by using a Factory Sensor. See also the examples at the end of the linked manual page, this gives you an idea on how to setup this sensor.

Kind regards.

nice it is solved
