MEMORY UTILIZATION ANALYSIS

摘要

An application records memory allocations and releases as they occur over time, and an analysis system presents characteristic memory utilization patterns to a user for review and analysis. A variety of sampling techniques are used to minimize the impact of this memory utilization monitoring on the performance of the application, and the analysis system is configured to estimate the overall memory utilization based on these samples. Because these samples of the memory allocations are taken continuously as the application is running, the analysis system can provide visualizations of the memory utilization patterns that allow a user to easily recognize anomalous behavior. The analysis system includes an interactive interface that allows the user to trace the cause of the presented memory utilization patterns, and provides statistics regarding memory allocation and release to guide the user in this analysis.
