There are many ways to generate thread dumps. As it is written in plaintext, the contents can be saved for reviewing later. It contains information about the thread’s stack, presented as a stack trace. Thread dump in JavaĪ JVM thread Dump is a listing of the state of all threads that are part of the process at that particular point of time. So, if something goes wrong, we can use thread dumps to inspect the state of our threads. This can boost the performance of an application as threads can utilize available CPU cores.īut there’s are trade-offs, e.g., sometimes multiple threads may not coordinate well with each other and a deadlock situation may arise. Each thread requires certain resources, performs certain activities related to the process. It contains all relevant information about the thread and its current state.Ī modern application today involves multiple numbers of threads. A thread Dump contains a snapshot of all the threads active at a particular point during the execution of a program. When the process is executing, we can detect the current state of execution of the threads in the process using thread dumps. All the threads within a process share the same memory space and are dependent on each other. This helps to achieve parallelism wherein a process is divided into multiple threads. A process is described in memory with important information such as variable stores, file handles, the program counter, registers, and, signals, and so on.Ī process can consist of many lightweight processes called threads. It can be executed by a processor or a set of processors. What is Thread?Ī process is a computer program which is loaded into the computer’s memory and is under execution. We will also discuss how it helps to pinpoint the issues and some of the analyzer you can use. Let’s talk about the thread dump, and how to analyze it.
