The Precise for J2EE Dashboard workspace provides a comprehensive overview of the health and status of all instrumented application server instances, based on the data collected according to the application instrumentation. The information displayed in this workspace pinpoints performance trends and issues in your application and offers clear navigational recommendations throughout Precise for J2EE for further analysis and handling.
See “About About the Activity workspace” on page 22. See “About the Statistics workspace” on page 39workspace and About the Statistics workspace.

The Dashboard workspace is divided into two (left and right) panes. The Main area (left pane) displays a list of all the instances monitored by Precise for J2EE and compares them in terms of performance and resource usage. The Association area (right pane) contains two tabs, each displaying overtime graphs of the instances’ instances' behavior. The Association area also features the Findings table, providing specific details regarding performance issues and advice for further analysis.

For more information regarding viewing the displayed data, see “Tables Tables for a selected time frame” on page 13frame.
Table 1 Instance table
| Column | Description |
|---|---|
| Status icon | Indicates one of four possible instance availability states:
|
| Instance | Name of the instance (JVM). |
| Server | Name of the server on which the instance runs. |
| Avg. Response Time (Sec) | Average time it took to process a service request for a specific instance. |
| Executions | Total number of executions during the selected time frame. |
| Memory | Average amount of memory used by all the executions of the instance during the selected time frame. |
| CPU | Average percentage of CPU time used by the instances during the selected time frame. |
| Availability | Average percentage of time that the instance was available within the selected time frame. |
| SLA Compliance | Indicates the extent to which HTTP entry point service requests complied with the instance’s predefined SLA thresholds. |
...
- Avg. Response Time (Sec) vs Executions. An overtime graph displaying a breakdown, by type, of the average response time for the instance, relative to the number of executions.
- Overtime trends. An overtime graph displaying the performance trends for the instance. The performance trends for the instance in the selected time frame are shown in color, and the performance trends for the instance in the previous and (if applicable) following time frame are shown in grayscale. This view provides the user with a greater overtime perspective of the instance’s performance patterns and behavior.
- Findings table. A table listing the findings detected in the selected time frame, displayed in order of severity. For more information, see “About About the Findings area” on page 11area.
