To open a process and view its child processes:
Start dynamic graphing. For instructions, see Starting Dynamic Graphing.
Click the Open icon ().
Select Open Process Tree.
Note: If no processes have been created, the Open Process Tree menu item is not selectable.
The process selection menu displays the eight most recently created top-level processes (processes with no parent). If the process you want to open is not displayed, select More to view additional processes.
Select the process from the process hierarchy or type the name of the process in the Process field and click OK.
Processes are represented by rounded bright green rectangles in the graph.
