If you want to learn about the architecture of the application, performance characteristics of the application, effectiveness of the engineering organization – lot of times (if not all the times), we will look at the Word documents, PowerPoint decks, Excel spreadsheets that have been put together by the engineers/managers/executives of that application. In these artifacts truth can be exaggerated, truth can be untold, truth can be misstated. In some cases, it can even contain lie. What do we mean by it?

GC logs are vital artifacts to troubleshoot memory/CPU related problems and optimize applications performance. In Sep 2017, the much-awaited java 9 got released. In this release, GC logging is re-implemented using Unified GC logging framework (JEP 271). Unified logging framework is a new initiative to introduce a common logging systems for all components of JVM (ompiler, gc, classload, metaspace, svc, jfr, …).

Enabling GC logging provides great benefits such as: reducing overall application response time, troubleshooting memory problems, forecast outages, and doing effective capacity planning… Contrary to common thinking, enabling GC logging doesn’t add any noticeable overhead to your application. Thus, we strongly recommend you enable GC logging on all your production servers.
