Monitoring Oracle Fusion Middleware 11-11

11.1.11 Monitoring Applications Deployed to a Cluster

If you deploy an application to a cluster, Oracle Fusion Middleware automatically deploys the application to each Managed Server in the cluster. As a result, there is an instance of the application on each server. There are times when you want to monitor the performance of the application on an individual server, and times when you want to monitor the overall performance of the application across all the servers in the cluster. For example, normally, you would manage the overall performance of the application to determine if there are any performance issues affecting all users of the application, regardless of which instance users access. If you notice a performance problem, you can then drill down to a specific instance of the application to determine if the problem is affecting one or all of the application instances in the cluster. Fusion Middleware Control provides monitoring pages for both of these scenarios: 1. From the navigation pane, expand Application Deployments. Fusion Middleware lists the applications deployed in the current domain. If an application has been deployed to a cluster, Fusion Middleware Control shows a plus sign + next to the application to indicate that it represents more than one instance of the application on the cluster.

Expand the cluster application to show each instance of the application, as shown in the following figure: 3. Monitor the overall performance of the application on the cluster by clicking the cluster application, or monitor the performance of the application on a single server by clicking one of the application deployment instances.

11.2 Viewing the Performance of Oracle Fusion Middleware

If you encounter a problem, such as an application that is running slowly or is hanging, you can view more detailed performance information, including performance metrics for a particular target, to find out more information about the problem. Oracle Fusion Middleware automatically and continuously measures run-time performance. The performance metrics are automatically enabled; you do not need to set options or perform any extra configuration to collect them. Note that Fusion Middleware Control provides real-time data. If you are interested in viewing historical data, consider using Oracle Enterprise Manager Grid Control. For example, to view the performance of an Oracle WebLogic Server Managed Server: 1. From the navigation pane, expand the farm, then WebLogic Domain, and then the domain. 2. Select the server to monitor. The Managed Server home page is displayed. 3. From the WebLogic Server menu, choose Performance Summary. The Performance Summary page is displayed. It shows performance metrics, as well as information about response time and request processing time for applications deployed to the Oracle WebLogic Server. 4. To see additional metrics, click Show Metric Palette and expand the metric categories. The following figure shows the Performance Summary page with the Metric Palette displayed:
