A new version of VisualVM, the tool that makes visualizing the performance of Java SE applications easier, has just been released. Looking at the release notes VisualVM 1.3 has several new features and enhancements:
- Sampler added to core tool
- Sampler and Profiler presets
- Remote Heap Dumps
- Monitoring of remote hosts
- Custom sorting of hosts, applications, coredumps and snapshots
- New Tracer framework for probes
- New Threads Inspector plugin
There's a post by Jiri Sedlacek on the NetBeans Profiler and VisualVM blog that goes through each change (including screenshots) to highlight what's different.
If you want to get your hands on the latest version you can download it from the VisualVM website. Eventually it will be part of the JDK release (VisualVM 1.2.2 is the version in Java 6 Update 21).
