OverviewFor large JAVA applications, fine testing is also hard to block all vulnerabilities, even though we have done a lot of good work during the testing phase, many problems are exposed in the production environment and are difficult to reproduce in a test environment. The JVM is able to record some of the operational state of the system when the problem occurs and store it in a heap dump file, providing an important basis for us to analyze and dia

The state of the thread is a very important thing, so the threads dump will show these states, through the analysis of these states, can get the health of the thread, and then discover possible problems. The state of the thread is defined in the Thread.state enumeration type: Public enum State {/** *

Thread dump is used to diagnose problems with Java applications and can be used to discover deadlock threads, and so on. It can get the thread, the thread running state, the identity, the call stack, the stack contains the full class name, the method executed, and the number of lines in the source code, and so on.

Thread dump: Name your thread and view system-Linux general technology-Linux programming and kernel information. The following is a detailed description. Although the integrated development environment (IDE) can provide good debugging settings for graphical applications, it does not allow you to debug multi-threaded Java server programs. Fortunately, there are
