VisualVM is an all-in-one visual troubleshooting and profiling tool for Java applications, integrating command-line JDK tools with lightweight profiling capabilities. It is built on the NetBeans Platform and supports monitoring, heap and thread analysis, and plugin extensions.
Use cases
- profile a java application to find performance bottlenecks
- monitor jvm memory usage and garbage collection
- analyze heap dumps to find memory leaks
- inspect threads and detect deadlocks in a running jvm
- troubleshoot a slow or misbehaving java process in production
- monitor cpu sampling of a java app
When to choose
- you need a free visual profiler and monitor for JVM applications
- you want an all-in-one tool replacing jconsole, jmap, jstack and similar JDK tools
- you need heap dump and thread dump analysis with a GUI
When to avoid
- you need profiling for non-JVM languages
- you require fully automated or CI-integrated performance testing rather than interactive troubleshooting
- you need a lightweight command-line-only tool
