We present the design, implementation, and evaluation of … periodically, during the execution of the program, it … The "normal" ranges of stable metrics, obtained by … used in conjunction with an anomaly detector to … previously unknown, in 5 large, commercial applications. … [p. 219] The key observation used by HeapMD is … relatively stable. … In particular, we focus on degree-based metrics … such as the percentage of heap vertexes with … [, and vertexes with indegree=1, indegree=2, outdegree=1, outdegree=2], which are sensitive to the structure of the heap-graph. … [p. 220] our current prototype results in a 2-3X … [p. 221] HeapMD produces few false-positives. … [p. 222] To assist with debugging, HeapMD enables call-stack … [approaches its limits].
