Enabling response time breakdown collection for specific page elements

You can enable response time breakdown for specific pages or page elements to see how much time is spent in each part of the application as the schedule runs. Enabling response time breakdown collection for only certain page elements can be useful if you want to minimize the amount of collected data. Enabling response time breakdown collection for a whole test or schedule can require substantial amounts of memory.

Before you begin

To collect response time breakdown, the data collection infrastructure must be installed, configured, and running on all computers that are used in the distributed application under test. To learn how to install and configure the data collection infrastructure, see the installation guide and Configuring the data collection infrastructure. If you enable response time breakdown collection for a test and the application servers are not running the data collection infrastructure, the following error is displayed: IWAY0159E The data collection infrastructure does not appear to be running on hostname. Please ensure that it is running and try again.

Procedure

  1. Open a test in the editor.
  2. Expand the list under Test Contents to display the pages or page elements of interest.
  3. Select the pages or page elements to collect response time breakdown data for. Under Test Element Details, select Enable response time breakdown. You might need to scroll down in the test editor view to display the Enable response time breakdown check box. The Enable response time breakdown check box is displayed only for elements that support response time breakdown data collection. The specific elements that support response time breakdown vary depending on the protocol (HTTP, SAP, Citrix, and so on).
    Note: Restricting the scope of the response time breakdown collection improves performance and memory utilization. Enable response time breakdown at as fine-grained a level as possible. Enabling response time breakdown at too broad a scope can greatly increase the time spent in areas with a large number of Java™ EE interactions.
    You are prompted to select an existing response time breakdown location or to add a new response time breakdown location.
  4. To add other response time breakdown locations, click Add on the Advanced page.
    • To add a new response time breakdown location, select Add New.
    • To add an existing response time breakdown location, select Add Existing.
    Add locations for every server from which to collect response time breakdown information.

Results

You have enabled response time breakdown data collection for the specified page elements.
