Quickly find your Java application process Id
In this post, we are going to discuss how to find your Java application process Id quickly. For certain monitoring tools like yCrash, you need to pass your application process Id as input. If you want to look for a more detailed post with several different options to find your application’s process Id, you can refer to this blog post.

Eclipse MAT is a powerful tool to analyze heap dumps. It comes in handy when debugging OutOfMemoryError. Eclipse MAT reports two types of object size: 1) Shallow Heap 2) Retained Heap. This video explains the difference between them and how they are calculated. Watch this video to know more!

In the series of chaos engineering articles, we have been learning to simulate various performance problems. In this post, let’s discuss how to simulate ‘java.lang.OutOfMemoryError: Java Heap space’ problem. This ‘java.lang.OutOfMemoryError: Java Heap space’ will be thrown by the application when the application generates more objects than the allocated heap size.
