Exercise 1: Finding more about your Bea Weblogic Server

Weblogic Server has released newer versions over a period of time. AppPerfect Agentless Monitor supports monitoring of weblogic server with 7.x and above versions. Weblogic 7.x and 8.x server could only run using JDK 13 or JDK 14 as the newer version of JDK were not released by then. Prior to JDK 15, each server had its proprietary JMX implementation. With JDK 15, JMX implementation was standardized and was part of JDK itself. This required significant changes with in the server to support JMX implementation using standardized approach. Weblogic 9.x and above runs using JDK 15 or more.

Excercise 2.1 explains the step to add Weblogic 7.x/8.x monitor and Excercise 2.2 explains the step to add Weblogic 9.x monitor.

Exercise 2.1: Add Bea Weblogic 7.x/8.x Monitor

Once we have identified the version of Weblogic server is 7.x or 8.x, we will proceed to add Weblogic 7.x/8.x monitor in Agentless Monitor.

Action:

  1. Select Monitors tab in the Web UI of AppPerfect Agentless Monitor. Select Add button to add a monitor.
  2. Specify IP address or Host name or both of the machine on which Weblogic server is running.
  3. Select Bea Weblogic 7.x/8.x in the Monitor Type combo.
  4. Specify unique Monitor ID for this Monitor.
  5. Leave other values in General section to be default and move to Bea Weblogic 7.x/8.x Options.
  6. In java.home property, provide the path of JDK 1.4.x or lower located on the AppPerfect Agentless Monitor machine. If you do not have it, please download and install it.
  7. Provide user name and password required to access the server. These are configured during installation of Weblogic server. Please contact your system administrator if you are not aware of it. By default, the user name is weblogic.
  8. Specify Server port of Weblogic server. Default value is 7001.
  9. Specify Installation folder of Weblogic server. If the server is running on remote machine, Please copy weblogic folder to AppPerfect Agentless Monitor machine and provide its path.
  10. Now we have provided all the properties of Bea Weblogic 7.x/8.x monitor.
    Weblogic Monitor properties
    Ensure that Weblogic server is running at the moment. Now, select Next to validate and get the Attributes that can be monitored for this server.
  11. You will see Attributes tree that shows all the MBeans exposed by Weblogic server.
  12. Select the attributes that you wish to monitor and select Next to configure selected attributes or select Finish to start monitoring these attributes using default settings.
Exercise 2.2: Add Bea Weblogic 9.x Monitor

Once we have identified the version of Weblogic server is 9.x or more, we will proceed to add Bea Weblogic 9.x monitor in Agentless Monitor.

Action:

  1. Copy %WLS_HOME%\server\lib\wlclient.jar jar to MONITOR_HOME\tomcat\webapps\monitor\WEB-INF\lib folder.
  2. Select Monitors tab in the Web UI of AppPerfect Agentless Monitor. Select Add button to add a monitor.
  3. Specify IP address or Host name or both of the machine on which Weblogic server is running.
  4. Select Bea Weblogic 9.x in the Monitor Type combo.
  5. Specify unique Monitor ID for this Monitor.
  6. Leave other values in General section to be default and move to Bea Weblogic 9.x Options.

  10. Now we have provided all the properties of Bea Weblogic 9.x monitor.
    Weblogic Monitor properties
    Ensure that Weblogic server is running at the moment. Now, select Next to validate and get the Attributes that can be monitored for this server.
  11. You will see Attributes tree that shows all the MBeans exposed by Weblogic server.
  12. Select the attributes that you wish to monitor and select Next to configure selected attributes or select Finish to start monitoring these attributes using default settings.
Exercise 3: Use Java 1.5/1.6 Monitor instead of Bea Weblogic 9.x Monitor

Once we have identified required information of Bea Weblogic 9.x server, we can also add standard Java 1.5/1.6 monitor to monitor Bea Weblogic 9.x server by providing using additional JAVA_OPTIONS. Bea Weblogic 9.x monitor is a monitor specific to Weblogic 9.x server and allows you to monitor all readable MBeans in the server where as Java 1.5/1.6 monitor is a generic monitor that can monitor all the JVMs running with JDK 1.5 or more.

In order to monitor a server with Java 1.5/1.6 Monitor, please set JAVA_OPTIONS environment variable before starting the weblogic server in its startup file. -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=7008 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false. Note: You can specify a different port if 7008 is blocked by some other process. For the purpose of this tutorial we are not using authentication, you can configure authentication using Monitoring and Management Using JMX guide.

Restart Weblogic server and refer to Java 1.5/1.6 Monitor tutorial for adding Java 1.5/1.6 Monitor.
