You can view the chain of calls for transactions and methods. The chain of calls answers the question "Whom did I call?"
You can also view the call stack statistics for methods. Call stack statistics answer the question "Who called me?"
Chain of call and call stack statistics data are shown in the measurements tree window. The title of the window changes depending on which kind of data you are viewing.
To set the point to which the measurements tree window relates, you must drag the orange time line to the desired spot.
To view transaction call chains, right-click a component and choose J2EE/.NET Diagnostics > Show Chain of Calls. The Chain of Calls window opens displaying the chain of calls from the parent transaction downwards.

You use the Chain of Calls window to view the components that the selected transaction or method called. In the following figure, all the calls in the critical path of the Start server-side transaction are displayed.

You use the Call Stack Statistics window to view which components called the selected component. In the following figure, the FileServlet.service was called by Start (Server), which was called by Start (Client), and so on, down to the transaction at the bottom of the chain.
