Having full visibility into both metrics and logs of the garbage collector gives you the necessary information to understand what is happening and react to that, to do garbage collector tuning. To fully understand the garbage collector’s work, we need two things – the metrics that describe how and when it was running and the logs that tell you what was happening exactly. This is why the garbage collector’s performance is one of the crucial JVM metrics for the overall performance of the applications running inside the Java Virtual Machine. Unlike languages like C/C++, we don’t have exact control over when the memory will be freed – freeing the memory is the garbage collector’s job. Such objects can have a longer or shorter life, but at some point, they stopped being referenced from the code. Well, at least in the vast majority of the cases. When an application written for the Java Virtual Machine is running, it constantly creates new objects and puts them on the heap. ![]() ![]() ![]() Application Performance Monitoring Guide.
