all: the bean you want to profile will need to implement ThreadMX https://www.javamex.com/tutorials/profiling/profiling_java5_threads_howto.shtml
import java.lang.management.*; ... ThreadMXBean threadBean = ManagementFactory.getThreadMXBean(); once we have ThreadMXBean we can interrogate threadIds and attributes monitored long[] getAllThreadIds(); ThreadInfo[] getThreadInfo(long[] ids, int maxDepth); we can "read" the thread info with getThreadInfo a wild guess would lead one to believe you are calling ThreadMXBean.dumpAllBeans() it would be helpful to parse the attributes of ThreadInfo objects that you are seeing in "dump format" https://docs.oracle.com/en/java/javase/11/docs/api/java.management/java/lang/management/ThreadInfo.html there is a JMX Client that will allow you to view ThreadInfo attributes called JConsole explained here: https://docs.oracle.com/javase/7/docs/technotes/guides/management/jconsole.html clear as mud? m. ________________________________ From: Lukasz Lenart <lukaszlen...@apache.org> Sent: Thursday, April 23, 2020 2:43 AM To: Struts Developers List <dev@struts.apache.org> Subject: Re: Struts benchmarking Here are some comparisons, does anybody now how to read this?
