Path measurement: Difference between revisions

#'''Monitored flows seen on both devices:'''The monitored flows describes all IPv4 and IPv6 connections that have been seen on both devices and are used for calculating the latency and packet loss. Only this traffic can be considered for the actual measurement. In a working setup, the value must be non-zero.

#'''Flows seen on both devices without matching packets:''' If a flow is seen on both devices but not a single packet matches on both sides, it indicates a potential network setup problem. This probably means the packet is somehow modified by a device in between both measurement points. This setup is not supported. Usually this value should be zero. Small non-zero values can be ok, if the first number of monitored flows is much larger.

#'''Unmonitored flows seen only on ''master'':''' This counter shows the number of IP connections that are only visible at the master device. It means that for those connections no matching client packet has been received. If the master device also sees network traffic that is not routed to the client device, this value can be non-zero.

#'''Unmonitored flows seen only on ''client''''': This is the same counter as for the master device, but counting the connections on the client device that have not been seen on the master. Again, if the client device sees traffic that is not routed to the master, it is fine to see non-zero values here.
