Prepare for Analysis

 To analyze the application, start with the following steps:

  1. Open the poisson_sendrecv.single.stf sample trace file.

  2. Go to Charts > Event Timeline to open the Event Timeline.

    Note

    When you open a new tracefile, Function Profile and Performance Assistant charts open by default. You can change the default chart in the Preferences dialog box (Options > Preferences > Tracefile preferences).

  3. In the Event Timeline, drag your mouse over a specific time interval to zoom into it.

  4. Zoom deeper into the trace by selecting the single iteration.

    This is the view of the zoom. The trace map shows the section within the trace that is displayed. The Event Timeline chart shows the events that were active during the selected time.
