InfoCenter Home > 6.6.0.12.2: Exploring the Resource Analyzer's graphic interfaceThis section describes the graphical interface for the Resource Analyzer. The following topics are included:
Layout of the consoleThe Resource Analyzer main window consists of two panes: the Resource Selection pane and the Data Monitoring pane. The Resource Selection pane, located on the left, provides a view of resources for which performance data can be displayed. The Data Monitoring pane, located on the right, displays numeric and statistical data for the resources that are highlighted (selected) in the Resource Selection pane. See The Resource Selection pane and The Data Monitoring pane for more information. 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 paneThe Resource Selection pane provides a hierarchical (tree) view of resources and the types of performance data available for those resources. Use this pane to select which resources to monitor and to start and stop data retrieval for those resources. The Resource Selection pane displays resources and associated resource categories in an indented tree outline. Clicking the plus (+) and minus (-) symbols expands and collapses the tree to reveal the 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 the instances they contain, 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 selection of counters 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. Below each application server, all resource categories are listed. If the enterprise beans category is expanded, all container instances in the server are displayed. All enterprise bean instances within that container appear below that in the hierarchy. A Methods resource is associated with each bean. 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 paneThe Data Monitoring pane enables the selection of multiple counters and displays the resulting performance data for the currently selected resource. It contains two panels: the Data Display panel above and the Counter Selection panel below. The Counter Selection panelThe Counter Selection panel shows the counters that are available to be selected for the resource performance category. Two factors determine the list of available counters in the Counter Selection panel:
The first three counters shown for each resource performance category are selected by default. All counters can be selected or deselected, and the resulting output, shown in the top panel, automatically reflects the selection. The columns in the Counter Selection panel supply the following information for each counter:
The Data Display panelWhen a counter on the list in the Counter Selection panel is selected, the statistics gathered from that counter are displayed in the Data Display panel at the top of the Data Monitoring pane. The View Data window shows the counter's output in table format; the View Chart window displays a graph with time represented on the x axis and the performance value represented on the y axis. One or more performance counters can be simultaneously graphed on a single chart. The chart plots data from n data points, where n is the current table size (number of rows). The display of multiple resources and aggregate dataWhen a single resource is selected in the Resource Selection pane, the Data Monitoring pane displays a choice of a table view or a chart view. If multiple resources are selected, the Data Monitoring pane displays a single data sheet for viewing summary information for the selected resources. The data sheet displays the tables for all objects of similar type 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. The Resource Analyzer provides aggregate data at the module level. See Figure 1 for a depiction of the data collection hierarchy used by the Resource Analyzer. 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 active enterprise beans of that home. Each container has an aggregate value that is the sum of all the enterprise beans in that container. The enterprise beans resource category (module) within the application server has an aggregate value that is the sum of all enterprise beans in all containers. The menu barThe menu bar contains the following options:
The toolbar iconsToolbar icons provide shortcuts to frequently used commands. The toolbar includes the following icons:
The node iconsIn the Resource Selection pane, the color of the node icon indicates the current state and availability of the application server in the domain.
This use of icon colors in the Resource Selection pane is identical to the use of colors for the node icons shown in the administrative console. In addition, in the Resource Selection pane, the following icon colors indicate whether performance data is being reported for a resource:
Note that even though data is continuously being collected for a particular resource, this data is not reported (not displayed by the Resource Analyzer) unless you explicitly enable data reporting for a resource from within the Resource Analyzer. See Setting the instrumentation level for instructions. The status barThe status bar across the bottom of the Resource Analyzer window dynamically displays the current state of the reporting values. The following state information is reported in the status bar:
