A system and method configured to instrument code for in-production monitoring provides a polling thread. A main thread executes the code of an instrumented application program and the polling thread executes in the background. Therefore the polling thread does not reduce the performance of the application program execution while monitoring activities are performed. Additionally, the polling thread is configured to simplify the process of instrumenting code for Java management extensions (JMX) by navigating the application program structure to locate administrative objects to bind to JMX and registering the administrative objects with JMX to enable monitoring of the instrumented code.
