java thread dump

DumpThread dump dumps the memory data (such as the call stack of the thread) that is related to threads. Thread dump is sometimes a javacore, but it seems that Javacore is an IBM virtual machine.GeneratedYou can use your own jstack generated Thread

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 {/** *

It mainly stores the running position of each Java application thread at a certain time point, that is, the method of the class to which the execution is performed and the line.

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
