Oracle Fusion Middleware provides a variety of technologies and tools that monitor server and application performance.
About Oracle Fusion Middleware Management Tools
Monitoring enables you to evaluate server activity, watch trends, diagnose system bottlenecks, debug applications with performance problems, and gather data that can assist in tuning the system.
After you install and configure Oracle Fusion Middleware, you can use the graphical user interfaces or command-line tools to manage your environment.
Each tool is described in Overview of Oracle Fusion Middleware Administration Tools in Administering Oracle Fusion Middleware.
The Oracle Process Manager and Notification Server (OPMN) is no longer used in Oracle Fusion Middleware. Instead, system components are managed by the WebLogic Management Framework, which includes WLST, Node Manager and the pack and unpack commands. See What Is the WebLogic Management Framework in Understanding Oracle Fusion Middleware.
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 that you are monitoring.
If you are new to Oracle Fusion Middleware or if you need additional information about monitoring your environment by using the Performance Summary pages, see Viewing the Performance of Oracle Fusion Middleware in Administering Oracle Fusion Middleware. 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.
Oracle Enterprise Manager Fusion Middleware Control
Fusion Middleware Control is a web browser-based, graphical user interface that you can use to monitor and administer your domain.
It can manage an Oracle WebLogic Server domain with its Administration Server, one or more Managed Servers, clusters, the Oracle Fusion Middleware components that are installed, configured, and running in the domain, and the applications that you deploy.
See Getting Started Using Oracle Enterprise Manager Fusion Middleware Control in Administering Oracle Fusion Middleware.
Oracle WebLogic Server Administration Console
Oracle WebLogic Server Administration Console is a web browser-based, graphical user interface that you use to manage an Oracle WebLogic Server domain.
It is accessible from any supported web browser with network access to the Administration Server.
See Getting Started Using Oracle WebLogic Server Administration Console in Administering Oracle Fusion Middleware.
Additional WebLogic Server Console Resources:
For details on the content contained in each summary table, see Monitor Servers in the WebLogic Administration Console Online Help.
For detailed information on using the WebLogic Server to monitor your domain, see Tuning Performance of Oracle WebLogic Server.
WebLogic Diagnostics Framework (WLDF)
The WebLogic Diagnostic Framework (WLDF) is a monitoring and diagnostic framework that can collect diagnostic data that servers and applications generate.
The WLDF can be configured to collect the data and store it in various sources, including log records, data events, and harvested metrics.
See Understanding the Diagnostic Framework in Administering Oracle Fusion Middleware.
For details on the WebLogic Diagnostics Framework and how it can be leveraged for monitoring Oracle Fusion Middleware components, see Configuring and Using the Diagnostics Framework for Oracle WebLogic Server.
WebLogic Scripting Tool (WLST)
The Oracle WebLogic Scripting Tool (WLST) is a command-line scripting environment that you can use to create, manage, and monitor Oracle WebLogic Server domains.
It is based on the Java scripting interpreter, Jython. In addition to supporting standard Jython features such as local variables, conditional variables, and flow-control statements, WLST provides a set of scripting functions (commands) that are specific to WebLogic Server. You can extend the WebLogic scripting language to suit your needs by following the Jython language syntax.
See Getting Started Using the Oracle WebLogic Scripting Tool (WLST) in Administering Oracle Fusion Middleware.
DMS Spy Servlet
The DMS Spy Servlet provides access to DMS metric data from a web browser.
Data that is created and updated by DMS-enabled applications and components is accessible through the DMS Spy Servlet.
Viewing Performance Metrics Using the Spy Servlet
The DMS Spy Servlet is part of the DMS web application. The DMS web application's web archive file is
dms.war, and can be found in the same directory as
The DMS web application is deployed by default as part of a JRF-enabled server instance. The URL is:
Only users who have Administrator role access can view this URL as access is controlled by standard Java EE elements in
Using the DMS Spy Servlet
Figure 4-1 shows the initial page of the Spy servlet: both sides show the same list of metric tables.
Figure 4-1 Spy Servlet Page - Metrics Tables
Description of "Figure 4-1 Spy Servlet Page - Metrics Tables"
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 4-2 shows the

To get a description of the fields in a metric table, click the Metric Definitions link below the table.
Native Operating System Performance Commands
Each operating system has native tools and utilities that can be useful for monitoring purposes.
Native operating system commands enable you to gather and monitor system activity information. For example CPU utilization, paging activity, swapping, and so on.
For details on operating system commands, refer to the documentation provided by the operating system vendor.
Network Performance Monitoring Tools
Your operating system's network monitoring tools can be used to monitor utilization, verify that the network is not becoming a bottleneck, or detect packet loss or other network performance issues.
For details on network performance monitoring, refer to your operating system documentation.
