Developers can easily identify the types of exceptions thrown and the number of times each exception occurred. A highlighting feature by YourKit is profiling thrown exceptions. It can run on a variety of platforms and also provides separate installations for each supported operating system which includes Windows, MacOS, Linux, Solaris, FreeBSD, etc.

Similar to JProfiler, YourKit offers some core features for visualizing threads, garbage collections, system memory usage, any potential memory leaks, and also offers support for local and remote profiling. YourKit can also be an excellent choice for Java profiling. JProfiler can be easily integrated with all popular and commonly used IDEs like Eclipse, NetBeans, and IntelliJ making it easier for developers to work with JProfiler on their preferred IDE. You can view memory usage for each object declarations and instances. It allows developers to monitor the current memory usage by all the running applications. Live memory is one feature of the highlighted feature by JProfiler. It also features advanced Java profiling for both SQL and NoSQL databases. It makes it very convenient for developers for Java profiling of applications that are running on remote machines. Jprofiler can be used for local as well as remote applications. This information is ideal to identify any need for optimization or elimination in the system. It is known for an intuitive user interface that provides separate interfaces for monitoring overall system performance, memory usage, potential memory leaks, and thread profiling. JProfiler is the first choice of many developers when it comes to Java profiling. If you are new to Java profiling or willing to learn about it, the following are some excellent Java profiling tools that have been the preferred choice of developers for Java profiling. It monitors and successfully performs some core operations like object creation, iterative executions, recursive calls, method executions, thread executions, and garbage collections. It is a tool that monitors the Java bytecode constructs and operations at the JVM level. Java profiling is performed using a profiler. This is where Java profiling comes into play.

If you are running the application locally, JProfiler will launch and will ask user to find the directory where JProfiler.exe is located, once you click OK, it will start the application server (from intelliJ RUN configuration).When it comes to developing a complex application, writing a Java code that just works fine is not enough. Java developers also need to monitor how the code performs internally like how memory is allocated to it, how it is integrating with other modules, implications of concurrent executions, areas where performance is not good, etc. Once you start IntelliJ for your web application either locally or remotely, you will see an icon on top right to start the JProfiler.

You can download JProfiler as a standalone tool to run or download a plugin with IntelliJ which is what I have done in my case. In this test, we will be profiling java code of the application. JProfiler combines time, memory and thread profilers in a single application. Thread Profiling – This analyses the thread synchronization issues. Memory Profiling – This provides the in-depth understand of heap usage by the application. Time Profiling – This measures the execution paths of your application on the method level. Before we run the test, we should understand the basic functionality of JProfiler and how it will help us in performance improvement. JProfiler (standalone or plugin in IntelliJ)įirst JProfiler is a tool to understand what is going on inside a running JVM.So as part of this past, I want to debunk few myths around this and why a developer should equally focus on a tool like JProfiler to check the performance. Especially since performance team members are not writing the code. This approach, despite might be working, can have its flaws. Many times, this is left to specialized performance teams or developers who know the tools well, but don’t know much about the code that they are trying to measure the performance. If you are a developer, some point of time you will have to use JProfiler for measuring the performance of your application.
