Java Profiling Agent

The Atatus Java Profiler helps troubleshoot Java application issues and detect performance bottlenecks before they impact users. It continuously captures method call stacks and runtime metrics in production, enabling you to identify slow methods, excessive CPU usage, high memory allocations, lock contention, and potential memory leaks.
