The ThreadMXBean doesn't work properly on Sun's JDK with a Linux 2.6 kernel It reports the total process cpu time for each thread. e.g. Try the following: | ThreadMXBean threadMBean = ManagementFactory.getThreadMXBean(); | long[] threads = threadMBean.getAllThreadIds(); | for (int t = 0; t < threads.length; ++t) | log(threadMBean.getThreadInfo(threads[t]).getThreadName() + " " + threadMBean.getThreadCpuTime(threads[t]) + "ms"); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3957339#...
