Stack Trace Table

This table is the body of the Stack Traces tab and contains aggregate stack traces for all events occurred during the period set on the Range Navigator. For each trace, it shows the number of events contributing to that particular part of the trace tree, as well as the total duration for the events contributing to that part of the trace.

Looking at a Trace

When you open the Stack Traces tab, the Stack Trace Table displays only the top-level method of each trace. To see the entire trace, click the right arrow next to the method name. Repeat this for each node until you locate a troublesome method or until all methods are open. To close the trace, click the minus sign (-) next to the method name. Repeat this action until you have closed all of the methods you no longer want displayed.

Customizing the Stack Trace Table

By using the Stack Trace table's context menu, you can perform the following:

Configuring the Trace Display

The label shown for each trace is comprised of a class name, a method name, its parameters, and its return value; for example:

Depicts two package names

While the method name always appears, you can configure how many of the other components actually appear by using the Trace Settings command on the context menu; for example, if you chose to hide all of the components, the above example will look like this:

Depeicts two lines of text in "tree" format

To configure the trace display:

  1. Right-click anywhere on the Stack Trace Table to open the context menu.

  2. Select Trace Settings.

    A context sub-menu opens.

  3. Select the component you want to display or hide:

    • Return Value

    • Class

    • Parameters

    A context sub-menu appears.

  4. Do either or both of the following:

    • Select or deselect Visible, depending on whether you want to display or hide the component.

    • Select or deselect Package Name, depending on whether you want to display of hide the package name.

Using the Stack Traces Table with the Operative Set

In the stack traces tree, you can add or remove the events contributing to a certain part of the trace to or from the operative set. This functionality, accessible from the Operative Set context sub-menu, is similar to that available on other Flight Recorder tabs.

To show just traces in the operative set on the Stack Traces Table:

You can display only the stacktraces for the events in the operative set by selecting Show Only Operative Set, at the top left of the graph. When you select this checkbox, only those traces you have added to the operative set will appear on the Stack Traces Table. In addition, the Range Navigator will show the impact of the set on overall activity by changing the color of their representation as a portion of the overall events.
