Application Response Time
The Application Analysis screen allows you to view the performance of a particular application over
time. It is accessed from Analyze > Response Time > Application.
The Transaction Time chart shows you the average transaction time for the application you have
selected. It is broken down into three components: Network Time, Server Response Time, and Data
Time.
The Other Metrics chart allows you to see information over time after you have selected the desired
metrics from the “Metric1” and “Metric2” drop-down.
Next are the Top Clients and Top Servers charts. These will show you the clients and servers with the
most bytes of traffic for the chosen application.
Network Response Time
After you have selected a client site and a server site, the chart will show you the transaction time of the
network link between the client site and server site. It is accessed from Analyze > Response Time >
Network.
