Web DDR Reports

Web DDR Reports are used to analyze the root cause of an issue, such as high level response time. User can see ND data from Drill-Down reports and can find out which method is taking more time to execute. User can see Drill down report in online as well as in offline mode.

To open the drill down reports, go to Sessions menu icon on the ND home page (in case of continuous monitoring). The session window is displayed. If sessions are not displayed there, click Show All button. User can apply filters also to search for a particular session.

 noteIn case of ND mode (non-continuous monitoring), user can view the drill down reports from the test run window in the same manner.

Select the check box corresponding to a particular session and click the down-arrow icon adjacent to the Reports button, and click the Web DDR option.

The system Queries window is displayed.

There are following Drill Down queries:

  • URL
  • Session
  • Transaction
  • DB Requests
  • Exception
  • Method Timing
  • FlowPath
  • Page
