Before you can report on overall WAN performance, you need to set a threshold that defines “good service.” The threshold is defined on the Response Time screen. For step-by instructions, see Set Thresholds in PacketGuide.
For traffic classes with total delay thresholds, PacketWise maintains lists of the "Worst Clients" and "Worst Servers." Each list displays up to 20 clients or servers that have the highest percentage of transactions exceeding the total delay threshold. These lists are useful for determining the scope of a problem and for focusing a diagnostic search. If you want PacketWise to track the worst performers in a class, you must first enable worst client and server analysis.
