Principle and implementation of monitoring Java object RecyclingA Monitoring the purpose of Java object RecyclingThe purpose of monitoring whether Java objects are recycled is to implement a memory leak alarm.Memory leak refers to

About 5 things you don't know about Java performance Monitoring-part 2nd: Java process monitoring with JDK built-in analyzer Fully functional built-in analyzers, such as Jconsole and VISUALVM, are sometimes more expensive than their performance costs-especially in systems running on production software. So, in the 2nd

I was so busy recently that I wrote last night that I fell asleep. Well, let's write the Java framework.Logs and certain monitoring in any system are very important. maintenance during the entire life cycle of a software is always a big headache at the same time, log and monitoring provides a good foundation and means for later maintenance. In

IntroductionThis article is the second article in the Java Performance Analysis tool series, the first article: Operating system Tools. In this article, you will learn more about Java applications and the JVM itself using built-in Java monitoring tools. There are many built-in tools in the JDK, including: Jcmd

Java itself does not directly listen to the system's file operation events, but you can first write the C + + call operating system API listening file, and then through the method of JNI call implementation. Limited to my C + + level, the interface is not implemented in C/C + +, and there are open source components jnotify implemented This feature, this example uses Jnotify.public class MainFrame extends JFrame ... {Private JPanel ContentPane;Private

If the Java program consumes more resources and is unstable, it can use its own VISUALVM tool for monitoring and performance analysis, and can also generate snapshots for further analysis based on the application snapshot functionality it provides. The procedure is as follows:1. Execute the "JVISUALVM" command under the CMD console or Linux terminal of Windows to enter the
