Memory utilization analysis

A method comprising:

• recording a plurality of records of memory allocations that instantiate objects and releases of the instantiated objects for an application as they occur in a system that is running the application,
• communicating the records of memory allocations and releases to an analyzer, each record including an identifier of the instantiated object,
• processing, by the analyzer, the records of memory allocations and releases to identify allocations and corresponding releases of the instantiated objects, to produce one or more memory utilization patterns, and
• displaying the one or more memory utilization patterns on a display device.

A non-transient computer readable medium that includes an application program that, when executed by a processor, causes the processor to:

• record a plurality of records of memory allocations and releases as they occur when the application program is executed,
• provide the records of memory allocations and releases for use by an analyzer to determine memory utilization patterns,
• wherein:
• each record of memory allocations and releases includes an identification of the allocation, a time of the allocation, an identification of a location in the application program associated with the allocation, and a time of the release;
• and
• the records of sampled allocations include records of a call stack for each sampled allocation and the analysis program causes the processor to display a visualization of a composite of one or more of the call stacks, or
• the records of sampled allocations includes an object class of each allocation and the analysis program causes the processor to display a visualization of memory utilization for one or more object classes.

A non-transient computer readable medium that includes an analysis program that, when executed by a processor, causes the processor to:

• access a plurality of records of sampled memory allocations and releases corresponding to an execution of an application program, the sampled memory allocations and releases being fewer than an entirety of the memory allocations occurring during the execution of the application program,
• process the records of memory allocations and releases to produce one or more memory utilization patterns, and
• display the one or more memory utilization patterns on a display device,
• wherein:
• each record of memory allocations and releases includes an identification of the allocation, a time of the allocation, an identification of a location in the application program associated with the allocation, and a time of the release;
• and
• the records of sampled allocations include records of a call stack for each sampled allocation and the analysis program causes the processor to display a visualization of a composite of one or more of the call stacks, or
• the records of sampled allocations includes an object class of each allocation and the analysis program causes the processor to display a visualization of memory utilization for one or more object classes.

An analysis system comprising:

• a processor, and
• an analysis program that is configured to cause the processor to:
• access a plurality of records of sampled memory allocations and releases corresponding to an execution of an application program, the sampled memory allocations and releases being fewer than an entirety of the memory allocations occurring during the execution of the application program,
• process the records of memory allocations and releases to produce one or more memory utilization patterns, and
• display the one or more memory utilization patterns on a display device,
• wherein:
• each record of memory allocations and releases includes an identification of the allocation, a time of the allocation, an identification of a location in the application program associated with the allocation, and a time of the release;
• and
• the records of sampled allocations include records of a call stack for each sampled allocation and the analysis program causes the processor to display a visualization of a composite of one or more of the call stacks, or
• the records of sampled allocations includes an object class of each allocation and the analysis program causes the processor to display a visualization of memory utilization for one or more object classes.
