Abstract
An approach is provided for monitoring of the activity in production computer systems. During a first period of time, substantially all of a first plurality of dispatches sent to a CPU are recorded. Each dispatch of the first plurality of dispatches indicates an initial instruction of a stream of instructions that is executed without interruption by the CPU. Based on the first plurality of dispatches, a baseline profile that indicates a normal execution flow in the system is generated. During a second period of time, substantially all of a second plurality of dispatches sent to the CPU are monitored. Based on the baseline profile and on at least one of the second plurality of dispatches, a determination is made whether an abnormal execution flow exists in the system during the second period of time. One or more actions are performed in response to determining that the abnormal execution flow exists in the system during the second period of time.
