Table 1 Information displayed in the execution tree
| Field | Description |
|---|---|
| Icon | Displays an icon reflecting the node type. |
| Name | Displays the name of the selected node. Depending on the tree view settings selected, the name will be displayed either its short name, or its full execution context. |
| Selected "Sorted by" value | Displays an aggregated value of the selected “sort by” option for the node’s entire underlying call tree. For example, the JDBC contribution to JVM response time will be an aggregation of all JDBC methods times of that JVM. |
To change the current tree view settings, see “Configuring Tree View Settings” on page 47.

Table 2 Information displayed in a node’s ToolTip
| Field | Description |
|---|---|
| Type | Displays the node’s method type. |
| Context | Displays the full execution context of the selected node. |
| Selected "Sorted by" type and value | Displays the field by which the tree view is sorted by and the value for the selected node and its underlying call tree. |
The table below describes the “sort by” options available for the execution tree.
Table 3 Sort options for the execution tree
| Sorted by | Description |
|---|---|
| Response Time (Avg) | Displays the average response time for each node and its underlying call path. The average response time is displayed in seconds. |
| Response Time (Sum) | Displays the total response time for each node and its underlying call path. The summed response time is displayed in hours: minutes: seconds: milliseconds. |
| Work Time (Avg) | Displays the average work time in seconds for each node. The average work time is displayed in seconds. |
| Work Time (Sum) | Displays the summed work time in seconds for each node. The summed work time is displayed in hours: minutes: seconds: milliseconds. |
| Executions | Displays the number of executions within each node. |
All of the sort options can be displayed in ascending or descending order. You can also select the maximum number of executions to display under each node, the maximum number of results to display, and whether to display the method’s long or short name.

Table 4 Analysis tabs available in the Precise for J2EE Activity workspace
| Tab Name | Description | Displayed for | For more information | ||
|---|---|---|---|---|---|
| Highlights | Displays a comprehensive performance overview of the node selected in the execution tree. This view reveals performance problems of the entire call tree invoked under the selected node. | All entities. | See “The Highlights tab” on page 26. | ||
| Load Balance | Displays information for the selected node throughout the monitored application. | All entities.
| See “About the Load Balance tab” on page 28. | ||
| Impact | Displays information regarding the selected node’s impact on the application. It displays general performance data for the selected node in the selected time frame and specific information regarding its contribution to all entry points and methods by which it is directly invoked. This view provides the user with a comprehensive overview of the specific method’s performance throughout the application. |
| See “About the Impact tab” on page 28. | ||
| Entry Points | Displays and compares performance data of the entry points in the selected time frame. This view enables efficient identification of problematic entry points. | Instances/All instances | See “About the Entry Points tab” on page 30. | ||
| SQL & Exit Points | Displays and compares performance data of the SQL and exit points in the selected time frame. This view enables efficient identification of problematic SQLs and exit points. | All entities except SQLs. | See “About the SQL & Exit Points tab” on page 31. | ||
| Methods | Displays information regarding all the methods and URI/iView invoked in the call tree under the selected node. The view provides a deeper look into a problematic node by showing comprehensive data for all invoked methods. | All entities except SQLs. | See “About the Methods tab” on page 32. | ||
| Locks | Displays all methods in the call tree under the selected node that were locked at any point. This view provides an overview of all locked methods and enables the user to see locking trends. | All entities except SQLs. | See “About the Locks tab” on page 33. | ||
| Exceptions | Displays data for exceptions thrown from the call tree under the selected node. This view pinpoints methods with a high exceptions rate. | All entities except SQLs. | See “About the Exceptions tab” on page 34. | ||
| Leaks | Displays the object allocation data for the call tree under the selected node. | Instances/All instances | See “About the Leaks tab” on page 35. |
The Highlights tab
The Highlights tab appears when any node type within the execution tree is selected, and displays a comprehensive performance overview of the selected node. The highlights tab provides information regarding performance trends for the selection’s underlying call path and displays performance findings to facilitate focused navigation to the root cause of a performance issue.

Table 5 Columns in the JVM Leak Candidates Allocated Directly and Indirectly table
| Item | Description |
|---|---|
| Chart Legend Color | Color icon showing the color representing the row in the graph. |
| Allocated Method | The method name where the object was allocated. |
| Object Type | The Object, Collection, Array, or String Buffer. It contains values such as: “Integer”, “String”, or “MyObject”. |
| Growth Rate (%) | Rate of growth (in percents) of the number of objects over time (objects/minutes). This column is default for sorting. |
| Live Objects Count | Number of live instances of an object. Live Objects Count can be displayed as a “waterfall” bar, or in numbers. |
