Overview

This plugins computes the Network Response Time as computed by the MMT. This tool computes this value for each detected flow as the time (in milliseconds) between the first packet from client to server and its response from server to client, i.e. the RTT. The plugin will rely on the aggregation framework of MongoDB to compute the average Network Response Time of the flows in the last completed minute.
