ABSTRACT:
A method, system and computer-usable medium for attributing memory usage are presented. The method includes the steps of creating an object graph of a portion of a memory heap, wherein the object graph includes nodes that represent objects and associated properties of the objects, and wherein the object graph includes connectors that represent relationships between the objects in the memory heap; observing nodes in one or more subgraphs of the object graph, wherein the nodes represent objects that are selected for observation by a pre-determined criteria; searching for characteristic node properties of nodes that are sampled, from the subgraph, for observation; searching for characteristic topological properties of the subgraph that sampled nodes participate in; and applying a set of pre-determined domain-specific pattern matching filters to the node characteristic properties and the topological characteristic properties to attribute memory usage to a proper software component in a system.
