Test Manager Guide
This guide describes how to keep track of the performance of the application by evaluating the test results. This guide is intended for test managers.
Logs overview
Rational® Performance Tester uses logs to store different types of information, which you can use to determine the reason for a test failure.
Viewing adjustments to page response times
To see the adjustments to page response times that are measured during a test run or a schedule run, open the test log for that run.
Disabling adjustments to page response times
Starting with Rational® Performance Tester Version 8.1.1, HTTP page response times are adjusted for increased accuracy by using advanced techniques to exclude processing overhead not related to the server under test. To configure the product to use the previous method for calculating page response times, set the RPT_VMARGS property rptPre811PageResponseTimes.

  - Logs overview
    Rational® Performance Tester uses logs to store different types of information, which you can use to determine the reason for a test failure.
    - Viewing test logs
      To see a record of all the events that occurred during a test run or a schedule run, as well as the status of each verification point, open the test log for that run. You can also compare an event from the test log with the request or response in the test to view the differences between the recording and the playback of the test.
    - Viewing errors while running tests
      To view errors and other events while a test is running, use the Execution Event Console view. If problems occur in a test run, you can examine the Execution Event Console view to determine whether to stop or continue the test.
    - Viewing reports after a run
      Reports are generated and displayed automatically after a run. Each test result begins with the name of the schedule or test, and ends with the timestamp of the run in brackets.
    - Accessing reports remotely
      Before executing a schedule or test, you can enable an option so that you can access reports remotely from a web browser. When you make changes to a report, the changes are saved to the workspace where the workbench is running.
    - Exporting test logs
      To process data from a performance test in another application or to use search tools to locate text in a test log, export the test log to a text file.
    - Exporting event log
      To view all the events that occurred during the run of a test from another file, you can export this data from the Event Log panel, to an XML, CSV, or text file.
    - Exporting event console output
      To view errors and other events of a test run from another file, you can export this data from the Execution Event Console view to an XML, CSV, or text file.
    - Viewing adjustments to page response times
      To see the adjustments to page response times that are measured during a test run or a schedule run, open the test log for that run.
      - Disabling adjustments to page response times
        Starting with Rational® Performance Tester Version 8.1.1, HTTP page response times are adjusted for increased accuracy by using advanced techniques to exclude processing overhead not related to the server under test. To configure the product to use the previous method for calculating page response times, set the RPT_VMARGS property rptPre811PageResponseTimes.
    - Viewing resource monitoring data
      You can analyze the performance of the computer resources, application server, or database servers by viewing the resource monitoring data in web analytics reports.

Disabling adjustments to page response times

Starting with Rational® Performance Tester Version 8.1.1, HTTP page response times are adjusted for increased accuracy by using advanced techniques to exclude processing overhead not related to the server under test. To configure the product to use the previous method for calculating page response times, set the RPT_VMARGS property rptPre811PageResponseTimes.

About this task

Typically, you do not disable adjustments to page response times unless you want to compare results gathered from versions of the product prior to 8.1.1 with results gathered from versions of the product starting with 8.1.1.

Procedure

In the Test Navigator, right-click the location on which to disable page response time adjustment.
Click Open.
Under Property Groups, click the General Properties link, and then click Add.
In the New Property window:
1. In the Property Name field, type RPT_VMARGS.
2. In the Operator field, confirm that the operator is =.
3. In the Property Value field, type -DrptPre811PageResponseTimes, and then click OK.
