View Results Offline

This section describes the Offline Results page which displays performance measurements and results for resources that were monitored in the test run. Viewing results offline provides quick access to performance graphs without having to wait for run results to be collated and analyzed.

The only difference in viewing results offline—compared to online—is that there is no data flow or runtime view; there is only a history view.

Note: This feature is provided as a tech preview version.

View test results offline

  1. Use one of the following:

    • From the Start Page: On the My Performance Center navigation bar, click Start. In the Finished section of the Runs pane, select a performance test and click Offline Results.

      Note: Only the four most recent test runs are displayed.

    • From the Runs module: On the My Performance Center navigation bar, select Run & Analysis >Runs. In the Test Runs pane, select a performance test and click View Offline.

    • From the Test Lab module: On the My Performance Center navigation bar, select Test Management >Test Lab. In the Performance Test Runs pane, select a performance test and click View Offline.

    Note: Offline results cannot be displayed if there was an error that did not allow the test to run, or if the results no longer exist (see Size and time limits for storing offline results below).

  2. The Offline Results page opens as a tab in My Performance Center with the name of the test run.

  3. For an explanation of the user interface elements in the Offline Results page, see Evaluate a test's status and View measurements and results for the test run below.

Evaluate a test's status

After a test run, the test summary contains general information about what happened during the test.

The summary pane provides the following data:

UI Elements

Description

<Run State>

The current run state, and the name and ID of the test.

Duration The time that the test took to run (HH:MM:SS).
Start Time The start date and time of the test run.
End Time The end date and time of the test run.
Hits Per Second

How many hits (HTTP requests) there have been to the Web server by Vusers during each second of the test run.

Throughput

The amount of throughput, in bytes, on the Web server during each second of the test run.

Errors

The number of Vuser errors that occurred during the test run. If there are errors, click the number of errors link to view details in the Messages view. For details, see Performance Test Run Page - Messages View.

Transactions

Bar chart displaying the number of completed, successful and unsuccessful transactions during the test run. Click the transactions link to view details in the Transactions view. For details, see Performance Test Run Page - Transactions View.

Total Vusers

The total number of Vusers that ran in the test.

Click to display a breakdown of the statuses of the Vusers in the performance test. For details, see View Results Offline.

Opens an area below the summary area, which displays the following:

  • Controller. The Controller that was used in the test.

  • Vusers Max. The maximum number of concurrent Vusers that ran in the test.

Select which graphs are displayed

  1. Click the Graphs button to display the offline graphs view.

  2. From the graph selection list on the right side of the pane, select which graphs to display in the Offline Graphs pane.

    UI Elements

    Description

    <Graphs tree>
    • <search>. Enables you to search the basic graphs by name.

    • Basic Graphs. Displays a list of the configured online graphs. Select a graph to display it in the Online Graphs pane.

    • Merged Graphs. Enables you to merge several graphs into one. To create a merged graph, click Add. In the graph editor, drag the graphs that you want to merge.

    • <Graph icons> Displayed to the left of the graph name:

      • Indicates the graph is currently being displayed in the Online Graphs pane.

      • Indicates an anomaly has occurred in the graph.

View measurements and results for the test run

Click the Graphs button to display the offline graphs view.

The online graphs display performance measurements for those resources being monitored in a performance test.

The following table summarizes display options.

UI Elements

Description

Enables you to filter measurements by name in the legend.

Show only visible. Hides the non-visible measurements from the legend.

Has Anomalies. Enables you to display only those measurements that have an anomaly.

  • Configure. Enables you to configure the selected graph. The following options are available:

    • Time Display. The time displayed on the x-axis.

      • Relative to Load Test start. Displays the amount of time that has elapsed since the beginning of the test (in hours, minutes, and seconds).
      • Controller clock. Displays the time on the Controller clock.
      • None. No clock or time is displayed
    • Scale. Scales measurements approximately so that they appear in the same range in the y-axis. This avoids measurements with smaller values appearing as flat lines with zero value. Select the desired scale:

      • Automatic. Each measurement in the graph is displayed in the scale that best suits it.
      • None. Each measurement's true values are displayed in the graph.
    • Apply to all visible graphs. Applies the changes to all displayed graphs.

  • Duplicate. Enables you to duplicate the selected graph.

  • Show Anomalies. Displays the anomalies sleeve and the plot bands for those measurements that have an anomaly.

Enables you to maximize/minimize the selected graph.

When you maximize the graph, the following information is displayed:

  • Expand Legend. Expands the area of the legend.

  • Filter Measurement. Enables you to filter measurements by name in the legend.

  • Show only visible. Enables you to hide the non-visible measurements from the legend.

  • Has Anomalies. Enables you to display only those measurements that have an anomaly.

  • Legend Options. (Displayed on left-hand side of the Name column.) The following options are available:

    • Show Favorites. Displays the measurements set as favorite.
    • Hide Visible. Hides the visible measurements on the graph.
    • Select Visible as Favorites. Saves the currently displayed measurements as favorites.
  • Name. The measurement name.

    A warning icon appears next to the name of each measurement that contains an anomaly.

  • Scale. The graph scale.

  • Max. The measurement's maximum value.

  • Min. The measurement's minimum value.

  • Avg. The measurement's average value.

  • Std. The measurement's standard deviation.

  • Last. The measurement's last value.

  • Measurement Options. (Displayed on left-hand side of the Set as Favorite icon.) The following options are available:

    • Show. Displays the measurement on the graph.

    • Hide. Hides the measurement from the graph.

    • Bold. Displays the measurement in bold.

    • Show/Hide Anomaly Sleeve. Shows or hides a sleeve (band) that indicates the expected behavior for the measurement. A plot band indicate deviations which are considered to be anomalies.

      Note: This option is not available when the Show Anomalies option is cleared in the  Graph Options menu.

    • Show only me. Displays the selected measurement and hides the others from the graph.

  • Set as Favorite. Sets the measurement as favorite.

  • <color>. Enables you to select in which color the measurement appears in the graph.

Size and time limits for storing offline results

The system administrator sets a size and time limit after which offline result files are deleted. By default, result files are deleted if they have not been opened for 30 days, or when the results folder exceeds 10 GB (the least used files are deleted first).

For details on configuring offline result settings, see Define host general settings.
