The Java Profiler for Every Developer

This view helps you visualize the call stack for a selected thread and see how it changes over time. The wider a stack frame is, the longer the method takes to execute. The colored blocks display native, library, and user code.

This view shows the percentage of the CPU time used by the methods, the method execution path in your application, and the total sample count. Call tree is useful for a quick overview of application activity and detection of critical execution paths.

This view shows a list of the methods executed while you were profiling your data. All of them are sorted by cumulative sample time. Each selected method has several views that show you either the method’s callers or callees.

This is a visual representation of threads activity over time. It is helpful for detecting unusual GC activity, multithreading issues such as livelocks, and so on.
