Execution flow

The Execution Flow view and table both show a representation of the entire program execution. In this view, the threads of the program fit horizontally, and time is scaled so that the entire execution fits vertically. In the table, the threads are grouped in the first column and time is recorded in successive rows.

In the Profiling Monitor view, select the <attached> J2EE Request Profile process and click the icon, or select Open With Æ Execution Flow (Figure | 7-29).

The bottom pane displays the action sequence. Expand the Web Container and select the first doPost method.

The top pane shows the execution stripes. Select the Zoom In icon and click into the Web Container column, near the start time of the method, until you see the graphic diagram appear.
