Abstract: According to one general aspect, a method may include monitoring the execution of at least a portion of a software application. The method may also include collecting subroutine call information regarding a plurality of subroutine calls included by the portion of the software application, wherein one or more of the subroutine calls is selected for detailed data recording. The method may further include pruning, as the software application is being executed, a subroutine call tree to include only the subroutine calls selected for detailed data recording and one or more parent subroutine calls of each subroutine calls selected for detailed data recording.

Abstract: According to an example implementation, a computer-readable storage medium, computer-implemented method and a system are provided to receive a first class, the first class indirectly implementing a first interface, wherein the first class extends a second class that directly implements the first interface, identify one or more directly implemented methods within the first class, determine a method signature for one or more of the directly implemented methods, estimate that the first class indirectly implements the first interface based on the method signatures for the one or more directly implemented methods, and instrument the first class based on the estimating that the first class indirectly implements the first interface.

Abstract: In a general aspect, a tracer is configured to instrument an application by injecting at least one interrupt instruction at a function entry point in a memory image of the application such that executable code of the application is not modified. The tracer is configured to collect information relating to execution of the application when the inserted at least one interrupt instruction is triggered during runtime of the application including tracing at least one operating system function used by the application at the function entry point. The tracer is configured to create an application signature based on the collected information. The application signature provides information about at least one system object accessed by the at least one operating system function.

Abstract: A software system is disclosed which facilitates the process of tracing the execution paths of a program, called the client. The tracing is performed without requiring modifications to the executable or source code files of the client. Trace data collected during the tracing operation is collected according to instructions in a trace options file. At run time, the tracing library attaches to the memory image of the client. The tracing library is configured to monitor execution of the client and to collect trace data, based on selections in the trace options file. Conditional tracing, through the use of triggers and actions taken in response to the triggers, allows the developer to control the tracing operation. The triggers can be conditional triggers in which the corresponding action is taken only if a conditional expression is satisfied. The system can trace multiple threads and multiple processes. The tracing system provides a remote mode and an online mode.
