Information in this document applies to any platform.



Purpose

For troubleshooting performance issues in UCM, getting insight into the Java Virtual Machine’s processes and resource usage can be vital in determining the source of performance bottlenecks. VisualVM is a useful tool in reviewing a running Java processes resources in real time. It allows for getting thread dumps and heap dumps on demand without the need to kill the UCM process. Moreover, it allows for Profiling the CPU or Memory usage of the UCM process, with the capability to profile just a single class file usage.

VisualVM is a “…visual tool integrating several commandline JDK tools and lightweight profiling capabilities. Designed for both production and development time use, it further enhances the capability of monitoring and performance analysis for the Java SE platform.”
