A deviance monitoring module is provided for examining various parameters of an operating system for deviance from a baseline behavior at specified intervals. A range of acceptable deviance values from a baseline behavior is set for parameters of an operating system. The parameters of the operating system are then monitored at specified intervals for deviance from the baseline behavior. In response to detecting that the deviance exceeds a predetermined threshold, the method triggers diagnostic data gathering on the parameters of the operating system according to an embodiment.

Monitoring and capturing early diagnostic data

A method for testing using a preserve status parameter in a computing system includes setting, by a calling process in the computing system, the preserve status parameter; issuing a call to a function under test by the calling process in the computing system; executing the function under test in the computing system, wherein data in a memory area accessed by the function under test during execution is preserved by the set preserve status parameter, such that the computing system does not reuse the memory area while the data in the memory area is being preserved; determining if an error occurred during execution of the function under test; in the event an error is determined to have occurred during execution of the function under test, making the data in the memory area available for inspection; and releasing the memory area for reuse by the computing system.
