Application Response Time Metrics are available on the response Response Time Summary Dashboard (Monitor > Response Time Summary), which allows you to see a “summary” view of the data.

To analyze Response Time data over time, use the selections found under Analyze > Response Time:

Application Response Time, page 3-22

Network Response Time, page 3-22

Server Response Time, page 3-23

Client Response Time, page 3-23

Client-Server Response Time, page 3-23

When you select Analyze > Response Time > Detailed Views, you will be able to select one of the following screens, each of which contains detailed lists of the response events.

Server Application Responses, page 3-23

Server Application Transactions, page 3-24

Server Network Responses, page 3-25

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.
