5.3 Monitoring the Performance of Oracle Fusion Middleware Components

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.

To view the performance of an Oracle Web Logic Managed Server:

  1. From the navigation pane, expand the farm, then WebLogic Domain, and then the domain.

  2. Select the server to monitor.

    The 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 show the Performance Summary page with the Metric Palette displayed:

    Description of metrics.gif follows
    Description of the illustration metrics.gif

  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. If there is no data available for those times, a confirmation message displays, explaining the timeline will be automatically adjusted to the time period for which the data is available.

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.

5.4 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.

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.

The Topology Viewer enables you to easily monitor your Oracle Fusion Middleware environment. You can see which entities are up and which are down.

You can also print the topology.

To view the topology:

  1. Click Topology.

    The Topology Viewer is displayed in a separate window.

  2. To see information about a particular target, place your mouse over the target. To view additional information, click More.

    The following shows the Topology Viewer window, with information about the Managed Server soa_server1:

    Description of topoview.gif follows
    Description of the illustration topoview.gif

With Topology Viewer, you can also:

Notes:

  • If you use Mozilla Firefox, when you click a link or menu item in the Topology Viewer to navigate back to the main Fusion Middleware Control window, the main window does not always get focus. For example, if you right-click a target node and select View Log Messages from the target menu, the focus remains on the Topology Viewer window. (If you go back to the main window, the Log Messages page is correctly displayed.)

    To work around this problem, make the following change in Firefox:

    From the Tools menu, select Options, and then Content. Click Advanced. In the Advanced JavaScript Settings dialog box, select Raise and lower windows.

  • If you use Internet Explorer, turn off the Always Open Popups in New Tab option.

5.5 Viewing Port Numbers

By default, Oracle Fusion Middleware assigns port numbers to various components and services during installation or when you create a component. (You can specify particular ports during installation and configuration.) You can view the assigned port numbers from the Port Usage page of Fusion Middleware Control.

You can view the port numbers of the Oracle WebLogic Server domain, the Administration Server, Managed Servers, or components, such as the SOA Infrastructure and Oracle Web Cache, using Fusion Middleware Control.

To view the port numbers that are currently used by a WebLogic domain:

  1. From the navigation pane, expand the farm, then WebLogic Domain.

  2. Select the domain.

  3. From the WebLogic Domain menu, choose Port Usage.

    The Port Usage page is displayed, as shown in the following figure:

    Description of ports.gif follows
    Description of the illustration ports.gif

    Optionally, you can filter the ports shown by selecting a Managed Server from Show.

The Port Usage detail table shows the ports that are in use, the IP Address, the component, the channel, and the protocol.

You can also view similar pages for the Administration Server, Managed Servers, and components, such as the SOA Infrastructure and Oracle Web Cache, by navigating to the target and choosing Port Usage from the target's menu.

Commands:

OPMN command:

opmnctl status l

WLST commands:

get('AdministrationPort')
get('ListenPort')
