Using the Resource Analyzer interface

This file describes the graphical interface for the Resource Analyzer. The following topics are included:


Overview of the console features

The Resource Analyzer is the graphical user interface for monitoring the performance of application servers, servlets, and other resources in WebSphere Application Server Advanced Edition. The Analyzer can be used for a range of monitoring tasks--from viewing real-time performance data, to gauging the load on servers over time, to evaluating the efficiency of resource allocations. The Analyzer provides the following features:

Note:
Not all performance data is displayed. The WebSphere Advanced Administrative Console provides a dialog box for specifying which data is to be collected for which resources. If data is not being collected for a particular resource, the data point is not registered and therefore cannot be displayed in the Resource Analyzer. See Setting levels for data collection.

Layout of the console

The Resource Analyzer main window consists of two panes: the Resource Selection pane and the Data Monitoring pane. The Resource Selection pane on the left provides a view of resources for which performance data can be displayed. The Data Monitoring pane on the right displays statistical and load data for the resources that are highlighted (selected) in the Resource Selection pane.

You can adjust the width of the Resource Selection and Data Monitoring panes by dragging the split bar left or right. You can rearrange the order of the table columns in the Data Monitoring pane by dragging the column heading left or right. You can also adjust the width of the columns by dragging the edge of the column left or right.


The Resource Selection pane

The Resource Selection pane displays resources and associated performance categories in an indented tree outline. Clicking the plus (+) and minus (-) symbols expands and collapses the tree to reveal performance categories for the various resource instances. The resource tree can also be navigated by using the up and down arrow keys to cycle through the branches and leaves and the left and right arrow keys to expand and collapse the tree of resources. Resource instances can be expanded to reveal their contained instances if applicable. For example, when a container instance is expanded, the enterprise bean instances in the container are revealed. The Data Monitoring pane automatically displays the appropriate table or chart view for any objects highlighted in the Resource Selection pane.

The first level of the hierarchy includes all nodes (machines) in the administrative domain, followed by all application servers on the node. Beneath each application server, all performance categories are listed. If the performance category named enterprise beans is expanded, all container instances in the server are revealed. All enterprise bean instances within that container appear below that in the hierarchy. Clicking an individual bean or container instance causes its corresponding counters to be displayed in the Data Monitoring pane. For enterprise beans, the counters displayed depend on whether the bean is an entity bean or a session bean. For containers, the counters are aggregate counters for all enterprise beans in the container.


The Data Monitoring pane

The Data Monitoring pane displays performance data for the currently selected resource. The following views are available:

When multiple resources are selected for monitoring, the Data Monitoring pane consists of a single Data Sheet. The Data Sheet displays the family tables for the selected resources. For example, if three servlet instances are selected, the Data Sheet displays a table of counter values for all the servlets, with totals. For most data, the total is a total of all the cells in the column. For statistical data, such as the average response time of a servlet, both the current and the average value is displayed. In that case, the value displayed in the Totals column is the weighted average of all the cells in the column.

Resource Analyzer provides aggregate data. If aggregate data is available for a group, it is displayed in the Data Monitoring pane. For example, for each enterprise bean home interface, counters track the number of beans of that home that are active. Each container has an aggregate value that is the sum of all the enterprise beans in that container. The application server has an aggregate value that is the sum of all enterprise beans in all containers.


The menu bar

The menu bar contains the following menu options:


The status and toolbar icons

In the Resource Selection pane, status icons indicate the availability of nodes and application servers in the domain. The icon colors are identical to those used in the administrative console:

The following icon colors indicate whether performance data is being reported for a resource:

Toolbar icons provide shortcuts to frequently used commands. The toolbar includes the following icons:
