I have a massive parallel Java-Application and want to measure its execution time the very same way that linux' time command does it (Real, User, System).

I'm especially interested in the time the application spends in kernel-tasks, i.e. shows suboptimal behavior (the higher the ratio of system/(system+user), the worse the performance).

In bash, there is time, for C++ there are boost/std chrono .. Is there anything for Java?

I found OperatingSystemMXBean, but it seems this is a dead end for measuring time in kernel-tasks.
