There are a few other profiling tools available in the market: There are many tools which are serving similar purpose that VisualVM is service. With application performance and memory utilization becoming so important these days, it obvious that profiling tools are in demand. Here are a few useful links for setting them up in IDEs: In cases where the interface doesn’t look interesting, you can integrate to different development IDEs like Eclipse, IntelliJ, NetBeans via the plugin provided. Here’s an interesting article about monitoring the IBM JVM with VisualVM. The purpose of CPU profiler is to determine how much time the CPU is spending when it executes the program and using this information you can optimize the code and improve the overall performance of the application. Similarly, the VisualVM-GC plugin will provide a graphical interface for the information regarding garbage collection. You can monitor and manage the MBeans of the application. The VisualVM-MBeans plugin will give programmers a MBean Browser to help you access the all of the platform MXBean instruments. a dump created using kill-3 command on Unix/Linux server where the application is hosted). You can either generate a heap dump, or you can read one you have generated outside this application (e.g. It can read and interpret binary heap dump files. It gives you a detailed analysis of heap space and utilization, classes and threads. ![]() The important tab here is the “Monitor” tab. Once the VisualVM application starts, you will see the list of applications on the left pane, and on the right side of the pane you will see different tabs. ![]() So if you see the above list, you can actually monitor your applications - both local and remote - which is quite handy in case of a run time exception, like outOfMemoryException, deadlocks, race conditions, etc., as you get to visually see which objects are causing an outOfMemoryException, for example, or the objects/resources causing thread deadlock. Heap dumps – very handy in analyzing the heap memory allocation.Thread dumps – very handy in case of deadlocks and race conditions.Analyzing the memory allocations to different applications.Monitoring of application’s memory usage and application’s runtime behavior.Visual interface for local and remote java applications running on JVM.There are many important features that VisualVM supports, such as: While setting up the remote application, you can give it name as well, “Display name.” Benefits To set a remote application profiling, you must connect to the remote server and add that application: The on top-left you can see application tab, and under this, you can see different options like Local, Remote and Snapshots. You can see all the running Java applications on the left pane of the interface. Once you are in the bin directory of JDK, you will find jVisualVM.exe just click on it, and the application starts up. The good news here, you actually don’t need to do anything, it is already available in the JDK bin directory. Official Page: How to Get and Run VisualVM ![]() VisualVM is free, and you don’t need to pay a separate cost to get this. With features like thread analysis and head dump analysis, it is very handy in solving run-time problems. It also helps to improve the application performance and ensure that memory usage is optimized. It helps the programmers and architects to track memory leaks, analyze the heap data, monitor the garbage collector and CPU profiling. All these tools are available in standard JDK distribution. It utilizes and integrates some of the command-line tools that JDK provides and bundles them up to see the application within JVM this bundle includes command-line tools jmap, jstack, jConsolem, jstat, and jinfo. VisualVM is a powerful tool that provides a visual interface to see deep and detailed information about local and remote Java applications while they are running on a Java Virtual Machine (JVM).
