I recommend you use the SIGAR API. Normal users would be unable to even attempt JMX access. Flight Recorder has been available in all JREs since Java 7 update 2 (April 2012). Although these are viable options, I would prefer not to maintain OS-specific code myself if someone already has a better solution.
By default JMX allows local connections to the process owner -- instead of username/password, you are authenticated by NTFS permissions (on Windows). All rights reserved. Choose your Java IDE Find out what to look for in a Java IDE and get tips for deciding which of the top three--Eclipse,...
We use this process very often in WebSphere Application Server Support, but it is not limited to that use or even to WebSphere Application Server. Java Cpu Usage High getProcessCpuTime longgetProcessCpuTime() Returns the CPU time used by the process on which the Java virtual machine is running in nanoseconds. As a result, developers can track down bugs that cannot be replicated outside of a production environment. Now, the best case scenario is to have only a few threads consistently consuming high cpu in the performance reports.
The investigation itself has been applied to many thousands of performance problems.
