How can I easily differentiate upload and download traffic with the packet sniffer?



Traffic can be differentiated on protocols. But I can't tell if the upload or download might be the bottleneck.

It would be great to be able to see total upload and total download in the graphs.

Use a combination of SNMP Traffic sensor and Packet Sniffer sensor.

The SNMP sensor easily gives you numbers for in and out traffic volume because the device simply counts traffic going into a port and out of a port.

With packet sniffing, what PRTG sees is a source IP and a destination IP, but PRTG can not decide which IP is inside your network and which is outside.

That is something you have to define with filters.

For traffic going out of your network to the internet add a filter e.g. SourceIP[192.168.1/24]

and a second Packet Sniffer sensor for the incoming traffic with the filter e.g. DestinationIP[192.168.1/24]
