Considerations when installing JDK in production servers instead of JRE Having said that, you can just install the specific tools that you want.

Garbage Collector Another common example would be clicking the Heap Dump button on the Monitor tab in VisualVM. 1: Java VisualVM profiler VisualVM lists all the Java processes that can be. VisualVM is quite good for Java/JVM profiling. Tools such as JProfiler and Yourkit leverage the native profiling tools.

Making Code Faster > I had to pay real money to get the Java profiler I used at AWS and while it worked, it was klunky, not fun to use.

This obviously represents a waste of resources.

Bulkhead pattern: semaphore vs threadPool After executing a load test that invokes for 60 seconds an and annotated method, you can see from a profiling tool picture, that the application only used 34 out of 514 created threads.

Overall, I’m glad that there’s another free tool out there for Java profiling. I also did not see much Thread blocking information displayed but I didn’t spend too much time with VisualVM, maybe it’s there. One thing that was missing in VisualVM was the “GC roots” option in YourKit. Profiling is the process of examining an application to locate memory or performance-related issues. VisualVM Thread and Heap DumpĪnd finally, the Heap Dump showed me the classes taking up the memory, just what I needed… VisualVM Classes View Unit tests enable you to test the code in Java applications. Compare Microsoft Visual Studio VS YourKit Java Profiler and find out whats.

The Heap and Thread dump is as easy as right clicking on the application and it was fast and seemed accurate. Java VisualVM enables you to take profiler snapshots to capture the results. The main view included CPU, memory, classes and threads graph as you would expect from a profiler.

This didn’t help me of course, so I turned to other tools. I’m guessing that since the server is under load, by the time YourKit could take the snapshot, the data was not relevant anymore. I could see the memory usage in the main graph but when I took a snapshot of the heap, the snapshot took a while, and it didn’t match with the graph I was observing. VisualVM will allow you to generate and analyze heap data, track down memory leaks, monitor the garbage collector and perform memory and CPU profiling, as well as being able to browse and operate. This time though I had to do profiling when server was under load and YourKit did not behave as I expected. Normally I use YourKit, easy to setup, and it has all the tools I need to do profiling such as CPU and Heap display graphs, force GC option, display of objects with their instance counts and sizes and so on. In the last couple of weeks, I had to do lots of profiling of our server code.
