Identifying phases of program execution

You can identify the following phases of program execution using the Execution Flow view:

Inactive periods
Computation

Preliminary steps

Follow these steps:

Select either the monitor or the agent resource in the Profiling Monitor view.
Right click, then select Open With > Execution Flow. The Execution Flow view opens.

Identifying inactive periods

Inactive periods are those with no active threads; on the graph, an inactive period is one with no colored bars. Read time (in seconds) along the right side. You can also see time in the status line.

Displays three bars with large open area at bottom; numbers along right side read 0.5 to 5.5 in 0.5 increments

Program shutdown would be indicated by the bottom of the bar corresponding to main--if the program was still being monitored.

Identifying computation

To examine the flow of execution during computation, follow these steps:

Click the Zoom In tool to enable it, then use the tool to enlarge a sequence of method calls in main.
Alternately, click the Select Zoom tool and then click and drag the mouse pointer to enlarge an area.
Move the cursor over any method's stripe and view details about it in the status line.
