Abstract
A diagnostic tool can dynamically instrument an application to collect program control flow information using one or more non-stopping production breakpoints. Analyzed program control flow information can be displayed. Dynamic code rewriting techniques can be used to change the production software without deploying new source code. The information collected at the non-stopping breakpoint can include the actual control flow that an instance of the production application took to reach the breakpoint in addition to information about the data. The analyzed control flow information can be visualized in a diagnostic tool allowing a user to see the path an execution of the program took to arrive at a particular breakpoint.
