Sun announced availability of Java VisualVM, an open-source GUI tool for troubleshooting and profiling Java applications. Users can view detailed information about Java applications while they are running on a JVM (Java Virtual Machine). Billed as an all-in-one troubleshooting tool, VisualVM integrates several command line JDK (Java Development Kit) tools and profiling capabilities. It enhances monitoring and performance analysis, according to Sun.
“After eight months of frantic development since VisualVM Preview 1 was released, I’m happy to announce the general availability of JDK 6 Update 7 Java VisualVM and VisualVM 1.0,” said Luis-Miguel Alventosa, a Sun senior software engineer, in a blog. Offered as part of Java Platform, Standard Edition (SE) Update 7, Java VisualVM provides a visual diagnostic tool for development and production environments. It includes such technologies as jvmstat, which provides lightweight performance and configuration instrumentation to the HotSpot JVM, as well as Java Management Extensions and the NetBeans profiler.
