Execution Statistics tab

The Execution Statistics tab displays statistics about the application execution time. It provides data such as the number of methods called, and the amount of time taken to to execute every method. Execution statistics are available at the package, class, method and instance level.

Before you begin

  • Launching or attaching to an application
  • In specifying profiling criteria, the Execution History - Statistical profiling set is selected or the Time Analysis with Show execution statistics (compressed data) profiling set is enabled in a custom profiling set.

The Execution Statistics view provides a number of controls to allow you to manipulate the information shown within the view:

  • Working with display modes
  • Working with columns
  • Filtering profiling data
  • Opening other views and tabs
  • Exporting the view data
  • Refreshing the view

About this task

Working with display modes

  1. There are four display modes available based on the four object types: packages, classes, methods, and instances. To switch between the package, class, method, and instance modes, select one of the following toolbar controls:
    • Package Level information Icon for package
    • Class Level information Icon for class
    • Method Level information Icon for method
    • Instance Level Information Icon for instance
  2. The data displayed can also be shown as percentages. To display the data as percentages, select Show as Percentage % icon in the toolbar.

The data displayed depends what object type is selected. The following table summarizes the data available in each display mode.

Column heading Package statistics Icon for package Class statisticsIcon for class Method statisticsIcon for method Instance statistics Icon for instance
Base Time: For any invocation, the base time is the time taken to execute the invocation, excluding the time spent in other methods that were called during the invocation. The summed base time for the classes in the package The summed base time for the methods in the class The time spent executing a given method Time
Average Base Time: The base time divided by the number of calls. Available Available Available Not Available
Cumulative Time: For any invocation, the cumulative time is the time taken to execute all methods called from an invocation. If an invocation has no additional method calls, then the cumulative time will be equal to the base time. The summed cumulative time for the classes in the package The time spent executing the methods in the class The time spent executing the given method. Time
Calls: The number of calls on the selected method. Not available Accumulated by class Count Not available
Cumulative CPU Time: The amount of CPU time spent in a method. Accumulated by package Accumulated by class Accumulated by method Not available
Note: The profiling views are described here using Java™. Profiling data from a different application context might change the terms and syntax used in the views. For more information, see Understanding application contexts in profiling views.

Working with columns

There are different controls available that allow you to manipulate the columns displayed in this view.

  1. To specify which columns to display in the view, select the Choose Column Choose column icon button in the toolbar drop-down menu Drop down arrow icon.
  2. In the Choose Columns dialog, select the columns that you want displayed in the view. Click OK to apply the changes.
  3. To show the change in each numeric column since the last refresh, select Show Delta Columns Show Delta icon in the toolbar.
  4. To sort column data, click the title of a column. Click the title of the column again to sort it in reverse order. The title of the column is prefixed with < if the column is sorted in ascending order or with > if it is sorted in descending order.

Filtering profiling data

Profiling filters can be applied to the Execution Statistics view to reduce the amount of data shown in the view. Profiling filters can be used across different profiling views as long as the view supports the filter. See the topic on Applying profiling filters for more details.

Opening other views and tabs

Other profiling views, tabs and source code views can be opened from the Execution Statistics tab.

  1. To open the Method Invocation tab on method, you need to be switch to the Package, Class or Method display mode. Select a method, right-click and select Show Method Invocation Show method invocation.
  2. To open the source code view of a selected object, right-click and select Open Source Open source icon.

Exporting the data in the view

The data within the Memory Statistics view can be exported to available report formats (for example, HTML or XML).

  1. To export the data in the view, select Report Export icon in the toolbar. The New Report dialog appears, showing available report types.
  2. Select the report type.
  3. Check the Open editor option to open the document using the default system editor.
  4. Click Next to continue.
  5. Select a parent folder and enter a file name.
  6. Click Finish to generate the report.

Refreshing the view

The Execution Statistics view can be refreshed using the Refresh Refresh Views icon button in the Profiling Monitor toolbar. When the view is refreshed, changes are marked with delta icons:

  • The delta icons Picture of a delta icon with the up arrow and Picture of a delta icon with the down arrow indicate that there is a change in the numeric value (increase or decrease respectively) for that particular cell since the last time the table was refreshed.
  • The diamond stylized diamond icon indicates new occurrences since the last time the Refresh Views A button with stylized icon button from the Profiling Monitor view was pressed.
