US Patent 7568185 Mechanism for program-assisted tracing actions

A method for tracing an instrumented application, including loading the instrumented application into a kernel level to obtain a corresponding instrumented process, registering a helper action with a tracing framework, tracing the instrumented process using the tracing framework, wherein tracing comprises triggering a probe in the instrumented process, determining whether the helper action is associated with the probe, and performing the helper action if the helper action is associated with the probe.
