java library to determine cpu and memory used by a program during its execution

Question

I want to measure the level of CPU and memory utilisation of a java program, preferably with a GUI and graphs showing exact utilisation levels throughout the period of execution of the program.

Is there a library/framework that does this?

Also, i would prefer if I could measure such usage for a program(either desktop or web app) that runs on local system or remote machine.

Answer 1

You can use Eclipse TPTP : http://www.eclipse.org/tptp/

It contains very good tools to follow the threads as well as the memory and cpu consumption, all inside a clear GUI. As every java profiler, it can be configured to follow a remote java program.

If you're using Eclipse as your IDE, this is a natural choice.

Answer 2

JProfiler is good to start with. You can connect it to a local or a remote java process and profile the application to understand the memory usage and various other performance counters.

Answer 3

我想说VisualVM将是一个好的开始。

Answer 4

还可以尝试VisualVM ，它完全免费地捆绑在oracle jdk中（不了解openjdk）。
