A profiler manager may attach and detach profilers from a running application. A profiler may be detached through a two step process where the profiler is sealed from communicating with the running application, then an evacuation step where the application is able to complete any responses that are pending. While the profiler is in the evacuation phase, another profiler may be attached to the application. Messages to the evacuating profiler may be captured and directed to the proper profiler.
