How to monitor IBM WebSphere Application Server using VisualVM

Here in this article we will try to monitor IBM WebSphere Application Server using VisualVM.

Test Environment

• IBM WebSphere JVM
• Oracle JDK6 update 7 or Later

Procedure

Step1: Start IBM JVM

Step2: Open the WebSphere admin console and go to below locations

Server -> Server Types -> WebSphere application servers ->[SERVER_NAME]

Expand Java and Process Management and click Process definition

Click Java Virtual Machine

In the Generic JVM arguments field enter the following properties:

-Djavax.management.builder.initial=
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.port=1099

Alternatively you can set the properties in the management.properties file located in the installation directory of the WebSphere application server.

Step3: Restart the JVM

Step4: Monitor the Websphere process using Visual VM

Go to the Oracle JDK installation directory.

Change to the bin directory and execute jvisualvm.exe.

In VisualVM start a new connection by selecting File – Add JMX Connection.

Enter localhost:1099 in the input field and click OK. VisualVM will connect to WebSphere. In the navigation tree on the left a new node should appear. Double-click this node to start profiling.

NOTE: With VisualVM you can to do the following

• Monitor heap usage
• Monitor CPU usage
• Monitor Threads
• Initiate garbage collections
• Profile CPU and memory
• And more…
