Which is best tool to audit specif network traffic flows ?

Dear Friends,
Being network engineer many times i want to know what kind of traffic / how
much traffic any specific user or computer is generating onto my network.

I have been using Solarwinds Orion Netflow Traffic Analyzer .. But it shows
only top -n flows. The problem , the computers which i want to observe do
not make too much traffic so it does not come in top 50 category.

I also tried .. live Netflow traffic Analyzer .. same problem.. ie is no
option there to get traffic analyses of node if that is generating very
less traffic..

Question is .... which tool you guys use or think is best that will give me
power to see traffic of any node that is passing through my network.

regards,
Rizwan
