      Info
      title Tip
      If you are connecting with a remote IP address instead of localhost, you need to bind the JMX service to the externally accessible IP address by adding the following system property to the product startup script stored in the <PRODUCT_HOME>/bin directory (wso2server.sh for Linux and wso2server.bat for Windows). For more information, read Troubleshooting Connection Problems in JConsole. Code Block -Djava.rmi.server.hostname=<IP_ADDRESS_WHICH_YOU_USE_TO_CONNECT_TO_SERVER> Be sure to restart the server after adding the above property.

   2. Enter values for the Username and Password fields to log in. If you are logging in as the administrator, you can use the same administrator account that is used to log in to the product's management console: admin/admin. 

      Info
      Make sure that the user ID you are using for JMX monitoring is assigned a role that has the Server Admin permission. See Configuring Roles for further information about configuring roles assigned to users. Any user assigned to the admin role can log in to JMX.
