I've got an app running on a grid of uniform java processes (potentially on different physical machines). I'd like to collect cpu usage statistics from a single run of this app. I've went over profiling tools looking for an option of automatic collection of data but failed to find any in netbeans, tptp, jvisualvm, yourkit etc.
Maybe I'm looking in a wrong way?
What I was thinking is:
but I can't find anything even remotely similar to this.
Any thoughts, experience, suggestions?
Thank you!

Profiling is the process of examining an application to locate memory or performance-related issues. When profiling a Java application, you can monitor the Java Virtual Machine (JVM) and obtain data about application performance, including method timing, object allocation and garbage collection.
JConsole is a built-in Java performance profiler that works from the command-line and in a GUI shell.
Java profiling in Eclipse allows you to optimize your code, streamline your application, and better understand your program.
If you have allowed remote JMX access and if you are using SUN JDK 1.6 then try using jvisualvm. It has the option of remote JMX connection. Though I haven't it used for profiling CPU in a distributed environment.
Note: For CPU profiling your application should be running on SUN JDK 1.6 or above.
