Individual application reports
NTA provides traffic trend statistics for the individual applications that were captured for the hosts for a
selected task. Individual application reports include the Application Traffic Trend report that displays the
average rate of traffic for the selected application and the TopN Application Usage List that identifies
which source and destination hosts contributed the greatest volume of traffic for the selected application.
Also included are reports for unknown TCP and UDP applications. Unknown applications are those
applications for which the Layer 4 TCP or UDP port number has not been assigned a name and is not
