Abstract
A method, system, and computer program product for profiling memory allocation in a data processing system are disclosed. The method includes initiating a memory allocation request and, in response to the memory allocation request, profiling the memory allocation request to determine a prescribed set of characteristics associated with request. The profiled set of characteristics are the stored for subsequent review. In one embodiment, the profiled memory allocation request is selectively chosen from a set of memory allocation requests on the basis of a memory allocation sampling criterion. The sampling criterion may be based upon the size of the memory block requested in the memory allocation request in one embodiment. In an alternative embodiment, the sampling criterion is the based upon the number of memory allocation requests. In an embodiment with multiple memory allocation routines, the memory allocation request may be of a first memory allocation routine type and the sampling criterion may be based upon the number of memory allocation requests of the first type. In one embodiment, the set of characteristics monitored by the application program includes the calling sequence that resulted in the memory allocation request. In one embodiment, the memory allocation request may be initiated by an application program written in the Java programming language and the memory allocation request is handled by a Java Virtual Machine.
