1. A computer program product for the dynamic instrumentation of a running software system, comprising: one or more machine readable storage media; programming logic provided by said machine readable media for programming a data processing platform to support dynamic instrumentation of said running software system, as by: establishing core instrumentation logic adapted to probe an operation of said software system and obtain data regarding said probed operation; said core instrumentation logic being independent of build parameters used to compile said software system; establishing dynamic instrumentation logic that provides build-dependent probed operation environment information to said core instrumentation logic; said probed operation environment information being dependent on build parameters used to compile said software system; and said core instrumentation logic being adapted to use said build-dependent probed operation environment information to probe an operation of said software system.
