Thread Dump is a snapshot of the status of all the threads at a particular time. Thread dumps are vital artefacts to diagnose CPU spikes, deadlocks, poor response times, memory problems, unresponsive applications, and other system problems. Thread Dump helps to find out what every thread in the JVM is doing at a particular point in time. A common phenomenon is once a high CPU usage is observed then thread dump analysis is required.
In some previous posts, I have shared articles which described Athlete, Atherosclerosis, Treadmill, Traffic Jam, All Roads Lead to Rome and Repetitive Strain Injury (RSI) Pattern. Today, you will see how to identify the bottleneck using Thread count. If thread count increased then it is a clear indication that some issues are there. To track the count of the thread named Stock Ticker Pattern. A simple and descriptive article published in the fastThread blog on this thread pattern along with the example. Refer the link. 👇
