2. JMX Monitoring :

   • Use JMX monitoring tools such as JConsole to connect to Tomcat's MBean server to view the status of Tomcat's thread pool. Select the MBeans tag in JConsole, and then find the ThreadPool node under the parent node org.apache.tomcat to view the status information of the thread pool.

     jstack -l <pid> > thread_dump.txt
     </pid>
