Abstract

The invention discloses a Java program performance problem positioning method, and the method comprises the following steps: obtaining JVM heap memory information, including object attributes in a JVMheap memory and a reference relationship between objects, and forming an object reference graph by the objects in the JVM heap memory; obtaining a memory consumption contribution degree PIC of each object type in the object reference graph; and positioning problems in the program according to the memory consumption contribution degree PIC. According to the method, the large-probability problem class can be more scientifically calculated by calculating the memory consumption contribution degree PIC, and the defects of inaccurate performance problem positioning and heavy manual analysis burdenin the current memory use analysis technology can be effectively solved through the concrete analysis.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a Java program performance problem location method and device. Background technique [0002] The most common performance problems in Java programs stem from memory. For example, memory errors in the JVM, excessive garbage collection, improper data caching, thread deadlocks and deadlocks, exhausted database connections, slow database calls, java code level issues, java application server bottlenecks, server performance issues, network latency and Connection problem. [0003] At present, mainstream Java program memory usage analysis technologies include MAT (Eclipse Memory Analyzer Tool) and JProfiler. MAT: a Java heap analyzer, analyzes the size of the memory occupied by each object type in the Java heap memory, and provides object reference relationships between object types. JProfiler: A Java program performance monitoring tool that provides Java software objects, ob...
