4.6.2 Using the DMS Spy Servlet

Figure 4–2 shows the initial page of the Spy servlet: both sides show the same list of metric tables. Figure 4–2 Spy Servlet Page - Metrics Tables Note that the Spy servlet can display metric tables for WebLogic Server and also for non-Java EE components that are deployed. For metric tables to appear in the Spy servlet, the component that creates and updates that table must be installed and running. Metric tables for components that are not running are not displayed. Metric tables with : in their name for example, weblogic_ j2eeserver:app_overview are aggregated metric tables generated by metric rules. To view the contents of a metric table, click the table name. For example, Figure 4–3 shows the MDS_Partition table. Monitoring Oracle Fusion Middleware 4-9 Figure 4–3 MDS Partition Table To get a description of the fields in a metric table, click the Metric Definitions link below the table.

4.7 Oracle Process Manager and Notification Server

Oracle Process Manager and Notification Server OPMN monitors the status of Oracle Fusion Middleware components. You can also start and stop system components, monitor system components, and perform many other tasks related to process management. For example, you can use OPMN to start and stop OPMN-managed processes, such as Oracle HTTP Server and Oracle Web Cache. For more information on OPMN commands, see Section 5.5.4, Monitoring Oracle HTTP Server .

4.8 Oracle Enterprise Manager 11g Grid Control

While Fusion Middleware Control provides real-time performance monitoring for a single Fusion Middleware Farm, Oracle Enterprise Manager 11g Grid Control enables you to centrally manage multiple farms, in addition to the rest of your data center such as the underlying host and operating system, databases, packaged applications such as Oracle E-Business Suite and Siebel, and third party products such as F5 BIG_IP Local Traffic Manager. Note: For more information on using OPMN, refer to Oracle Fusion Middleware Oracle Process Manager and Notification Server Administrators Guide.
