11 Monitoring Oracle Fusion Middleware

This chapter describes how to monitor Oracle Fusion Middleware using Fusion Middleware Control, Oracle WebLogic Server Administration Console, and the command line. It describes the following topics:

Note:

For information about monitoring servers for IBM WebSphere, see "Managing Oracle Fusion Middleware on IBM WebSphere" in the Oracle Fusion Middleware Third-Party Application Server Guide.

11.1 Monitoring the Status of Oracle Fusion Middleware

Monitoring the health of your Oracle Fusion Middleware environment and ensuring that it performs optimally is an important task for the administrator.

Oracle Fusion Middleware provides the following methods for monitoring the status of your environment:

Most of the monitoring tasks in this chapter describe how to monitor using Fusion Middleware Control or the command line.

The following topics provide more detail:

11.1.1 Viewing General Information

You can view the overall status of the Oracle Fusion Middleware environment from the home page of the farm using Fusion Middleware Control. This page lists the availability of all components, an application deployment summary, including SOA composites, if any SOA composite applications are deployed.

To view the overall status, from the navigation pane, select the farm.

The farm home page is displayed, as shown in the following figure:

11.1.2 Monitoring an Oracle WebLogic Server Domain

You can view the status of a domain, including the servers, clusters, and deployments in the domain from the domain home page of Fusion Middleware Control:

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

  2. Select the domain.

    The domain home page is displayed, as shown in the following figure:

    Description of the illustration webcenter_app.gif

See Also:

"Understanding WebCenter Performance Metrics" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter for more information about service metrics

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.

  2. Expand the cluster application to show each instance of the application, as shown in the following figure:

    Description of fmc_nav_cluster_app.gif follows
    Description of the illustration fmc_nav_cluster_app.gif

  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:

    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.

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.

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 workaround 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.
