Hello, pardon me if this is too simple but i cannot find any answer for this.
Sflow is sample based, which means for every X number of packet, 1 gets picked and gets sent out to collector immediately, so in this case, how can this single packet includes all the fields necessary? for example, for http traffic, if the sampled packet does not carry URL, how can I get URL? similar case, for radius traffic, how can i get Username? It is very likely the sampled packet does not carry this information at all. Am i wrong? Thanks
