YourKit Java Profiler is a reliable profiling tool specially designed for Java developers that need a fully featured CPU and memory profiling app.

Advanced CPU and memory profiling utility for all Java developers

Thanks to YourKit Java Profiler’s powerful analysis capabilities, you can determine CPU and memory hot spots, make comparisons, detect memory leaks, generate memory distribution reports and measure the shallow and retained size of objects.

What is more, the On-demand profiling feature offers you the power to enable profiling only when you need it and keep the application running at full power for the rest of the time. Hence, you can check the current heap state at any given moment by capturing memory snapshots.

Quick and easy installation

To start using YourKit Java Profiler, you just have to download the light archive and extract the application to a location of your choice. Moreover, YourKit Java Profiler seamlessly integrates with most popular IDEs and application servers.

YourKit Java Profiler comes with a user-oriented interface with support for keyboard shortcuts and report filtering for instant and in-depth analysis. The top toolbar helps you capture performance snapshot, initiate or stop the CPU profiling, clear all CPU profiling results, disable Stack telemetry, capture memory snapshots, start memory allocation recording and more.

Detailed graphs and handy filtering options

You also have the power to setup a number of actions that can be triggered by various events, such as high CPU or memory usage or the execution of a given method. The graphs generated in the CPU, Threads and Memory tabs, as well as those from the Garbage Collection and Performance Carts tab are updated in real time.

As follows, you can effortlessly monitor CPU usage, thread count, heap memory, non-heap memory, loaded classes, along with the minor and major collections.
