Monitoring a System Component

11-12 Oracle Fusion Middleware Administrators Guide 2. 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: Monitoring Oracle Fusion Middleware 11-13 5. Select a metric to add it to the Performance Summary. 6. To overlay another target, click Overlay, and select the target. The target is added to the charts, so that you can view the performance of more than one target at a time, comparing their performance. 7. To customize the time frame shown by the charts, you can: ■ Click Slider to display a slider tool that lets you specify that more or less time is shown in the charts. For example, to show the past 10 minutes, instead of the past 15 minutes, slide the left slider control to the right until it displays the last 10 minutes. ■ Select the calendar and clock icon. Then, enter the Start Time and End Time. You can also view the performance of a components, such as Oracle HTTP Server or Oracle SOA Suite. Navigate to the component and select Monitoring, then Performance Summary from the dynamic target menu.

11.3 Viewing the Routing Topology

Fusion Middleware Control provides a Topology Viewer for the farm. The Topology Viewer is a graphical representation of routing relationships across components and elements of the farm. You can easily determine how requests are routed across components. For example, you can see how requests are routed from Oracle Web Cache, to Oracle HTTP Server, to a Managed Server, to a data source. The Topology Viewer enables you to easily monitor your Oracle Fusion Middleware environment. You can see which entities are up and which are down. Note: To view relationships between Oracle WebLogic Server, Oracle Web Cache, and Oracle HTTP Server, each target must be running and show its status as Up.
