Abstract: Provided is a method and system for monitoring and analysis of networked systems, that is non-intrusive and real time. Both secure and non-secure traffic may be analyzed. The provided method involves non-intrusively copying data from a communication medium, reconstructing this data to a higher level of communication, such as the application level, grouping the data into sets, each set representing a session, and organizing the data for chosen sessions in hierarchical fashion which corresponds to the hierarchy of the communicated information. If monitored communications are encrypted, they are non-intrusively decrypted in real time. Hierarchically reconstructed session data is used by one or more plug-in applications, such as alarms, archival applications, visualization applications, script generation applications, abandonment monitoring applications, error detection applications, performance monitoring applications, and others.

Abstract: A method for facilitating network communications from one or more independent execution threads by a dedicated worker thread. Because an operating system is not designed for use with a large number of threads, such a system requires the use of multiple computers for simulating a large number of virtual users. This increases complexity, as well as cost. The present invention reduces the number of threads needed, which reduces resource needs, and in turn increases the number of virtual users that can be simulated. According to the present invention, a worker thread uses non-blocking function calls to efficiently handle requests for network operations.

Abstract: The present invention relates to a method and apparatus for providing automatic context management for simulating virtual users for testing and monitoring web applications, including those web applications that execute code on the client side, without requiring the actual execution of client side web application code or the execution of the client within the testing, monitoring, or simulation tool. Simulation tools with automatic context management according to the present invention can record and replay context-full scripts that do not require manual customization and are capable of handling state information even for web applications that execute code on the client side. These scripts are able to realistically mimic complex web application transactions on the network HTTP layer.
