Understand User Expectations Define Your Performance Objectives

4-2 Oracle Fusion Middleware Performance and Tuning Guide ■ Network Performance Monitoring Tools. See Section 4.10 . Use these tools, rather than directly editing configuration files, to perform all administrative tasks unless a specific procedure requires you to edit a file. Editing a file may cause the settings to be inconsistent and generate problems. Both Fusion Middleware Control and Oracle WebLogic Server Administration Console are graphical user interfaces that you can use to monitor and administer your Oracle Fusion Middleware environment. You can perform some tasks with either tool, but, for other tasks, you can only use one of the tools. For more information on using WebLogic Server Administration Console for monitoring your domain, see the Oracle Fusion Middleware Administrators Guide.

4.1.1 Measuring Your Performance Metrics

Metrics are the criteria you use to measure your scenarios against your performance objectives. You can use performance metrics to help locate bottlenecks, identify resource availability issues, or help tune your components to improve throughput and response times. After you have determined your performance criteria, take measurements of the metrics used to quantify your performance objectives. For example, you might use response time, throughput, and resource utilization as your metrics. The performance objective for each metric is the value that is acceptable. You match the actual value of the metrics to your objectives to verify that you are meeting, exceeding, or failing to meet your performance objectives. When you manage or monitor an Oracle Fusion Middleware component or application with Fusion Middleware Control, you may see performance metrics that provide insight into the current performance of the component or application. In many cases, these metrics are shown in interactive charts; other times they are presented in tabular format. The best way to use and correlate the performance metrics is from the Performance Summary page for the component or application you are monitoring. The next sections of this chapter provide an overview of the Oracle Fusion Middleware technologies and tools that can be used to monitor Server and Application performance. If you are new to Oracle Fusion Middleware or if you need additional information about monitoring your environment using the Performance Summary pages, see Viewing the Performance of Oracle Fusion Middleware in the Oracle Fusion Middleware Administrators Guide. In addition, the Fusion Middleware Control online help provides definitions and other information about specific performance metrics that are available on its management and monitoring pages. See Section 4.2.1, Viewing Performance Metrics Using Fusion Middleware Control .

4.2 Oracle Enterprise Manager 11g Fusion Middleware Control

Fusion Middleware Control is a Web browser-based, graphical user interface that you can use to monitor and administer a farm. Fusion Middleware Control organizes a wide variety of performance data and administrative functions into distinct, Web-based home pages for the farm, domain, servers, components, and applications. The Fusion Middleware Control home pages make it easy to locate the most important monitoring data and the most commonly used administrative functions—all from your Web browser. In addition, Fusion Middleware Control provides a set of MBean browsers that allow you to browse the MBeans for a WebLogic Server or for a selected application and perform specific monitoring and configuration tasks from the MBean browser.
