They need to monitor the realtime behavior of the application to give uninterrupted service to the end users, but monitoring is even important to the support teams to track down the issues of the applications. Doing support is the most important phase of the software development life cycle after delivering the product. End Users reported  different kind of issues and support engineers need some informations which are related to the application behaviour to solve the issues. Some issues are domain related and we can simply recreate the issues in our local environment. Fixing the issue is not a big deal if we could reproduce the same behavior in our local setup but some issues are not easy to replicate in the local environment because those aren’t continuously happening in the prod

1. Download JConsole topthreads Plugin. 2. Add following entries to the PRODUCT_HOME/bin/wso2server.sh     -Dcom.sun.management.jmxremote \     -Dcom.sun.management.jmxremote.port=PORT \     -Dcom.sun.management.jmxremote.ssl=false \     -Dcom.sun.management.jmxremote.authenticate=false \     -Djava.rmi.server.hostname=IP_ADDRESS \ Define your IP_ADDRESS address and PORT (port should be not used anywhere in that instance) 3. Run the JConsole using following command.     jconsole -pluginpath PATH_TO_JAR/topthreads-1.1.jar 4. Copy "JMXServerManager JMX Service URL" from the wso2carbon logs after restart the Wso2 Server (Eg:- service:jmx:rmi://localhost:11111/jndi/rmi://localhost:9999/jmxrmi) to the Remote process with the username and password. 5. Under Top Threads tab you can monitor the thread CPU usage.

We cannot use cipertool to automate encryption process for the selected elements in the jndi.properties file, because we can only specify Xpath notation here, but still we can use the manual process. Sample  [ESB_home]/repository/conf/ jndi.properties  file # register some connection factories # connectionfactory.[jndiname] = [ConnectionURL] connectionfactory.QueueConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist ='tcp://localhost:5672' # register some queues in JNDI using the form # queue.[jndiName] = [physicalName] queue.MyQueue = example.MyQueue # register some topics in JNDI using the form # topic.[jndiName] = [physicalName] topic.MyTopic = example.MyTopic 1. Enable secure valut in the ESB sh ciphertool.sh -Dconfigure 2.   Go to the [ESB_home]/bin and execute the following command to generate the encrypted value for the clear text  password. sh ciphertool.sh 3.   It will prompt following  console for input value.   Answer: wso2carbon [Ple
