JPROFILER MEMORY LEAK HOW TO
View Image 3 How to monitor performance 3.1 Intuitive understanding The error prompts you to check "Keep VM alive" and edit your saved session in the Start Center→Profiling Settings tab→Customize Profiling Settings→ Miscellaneous→Keep VM alive. During the monitoring process, if tomcat shuts down unexpectedly, an error like the following will be reported at this time. The session you saved in JProfiler, if you double-click to run it, its essence is to call startup.bat to start, so if you have manually enabled tomcat and then start this session in JProfiler, an error will be reported at this time -The port is occupied Ģ. bat → keep the default port 8849 → start.ġ. The details are as follows:Ĭlick Session→Integration Wizards→New Server Integration→Apache Tomcat 7.x→On this computer→check your JVM information→Waif for a connection from the JProfiler GUI (that is, JProfiler helps you start tomcat)→select your startup. Below we explain how to monitor this local tomcat7 server. For example, the name of the project on hand is DSPMSU_For_Display and the tomcat server is version 7.x. Suppose you have a project on hand that you want to publish on the tomcat server. View Image 2.2 Configure tomcat project and enable monitoring
In the Main class Select your compiled class file and press confirm step by step.Īfter the configuration is complete, you can start by double-clicking the session. Select the Launch mode and click the Application button 2. How to make this Helloworld run? You need to use the javac command under cmd to compile Test.java into Test.class, then click the red box on the upper right of the figure above, and then perform two configurations: 1. Here is just to explain to you how to use this technique. However, the recorded "Helloworld" session cannot be run. When we close, JProfiler will prompt us whether to save the current session, we click save, and then we can directly call this session in Session→Start Center. At the end of this chapter, there is a little trick for everyone. Step 7, about some detailed usage methods, we will explain below. Step 6, through the above operations, we can see the monitoring interface of JProfiler When jProfiler starts, it will automatically capture the running J2SE and J2EE programs, as shown below, select and click OK (tips: you can also click "Show Services" to refresh manually, JProfiler will automatically capture the running for you Java program ).Ĭheck the record CPU and record the allocation at startup, the other defaults can be left unchanged.
Step 4, let us start the journey of jProfiler with a small test example, write the program as follows, and run it. After the operation is successful, we can see the JProfiler extension plug-in in Eclipse as follows: Assuming that we are developing with Eclipse, click Session→IDE Integrations, select your Eclipse version, click OK and follow the prompts. Select "Evaluation" to indicate evaluation and trial.

Just imagine, how do we test the robustness and feasibility of the project we publish on the server? How to make a qualified and assured product? The answer I gave is to perform data collection and data monitoring under load testing, and adjust your code or configuration to make your project run optimally. In short, it can avoid memory leakage by evaluating CPU, memory, and threads. JProfiler's intuitive GUI allows you to find performance bottlenecks, catch memory leaks (memory leaks), and solve threading problems. It allows two memory profiles to evaluate memory usage and dynamic allocation leaks and CPU profiling to evaluate thread conflicts. Before starting, I asked myself, why should I learn jProfiler?īefore answering, let us take a look at what jProfiler is: JProfiler is a commercially authorized Java profiling tool developed by EJ Technology Co., Ltd.
