The CPU time is represented by a relative percentage and a ticks value. A tick represents a sample of the system taken by tprof (on AIX) or OProfile (on Linux on Power System). By default the ticks number is not displayed. To enable the display of ticks first open the preferences dialog from the main menu at , then navigate to the preferences page found under . Under Timing Data select show both percentage and ticks.
| Column | Description |
|---|---|
| Function | Shows the function or method name for C/C++ and Java/JNI applications or the procedure name for COBOL applications. |
| Hotness | Shows the hotness of a function using color. |
| % | Shows the percentage relative to the CPU time of parent filter in the Process Hierarchy Tree. Example: if you select My Application, the percentage is relative to the total CPU time sampled on My Application. |
| Ticks | Shows the total number of ticks recorded against the function. This column is only shown if the Show both percentage and ticks option is enabled on the Performance Advisor Appearance preference page. |
| Source | Shows the source file name that contains the function. |
| Module | Shows the module name that the function belongs to. |
The Whole System Overview page is displayed when the Whole System node is selected.

The filter box above the table can be used to filter the contents of the table. As you type into the box the contents of the table are filtered and the part of each function name that matches the filter is highlighted. Two wildcards are accepted: '*' matches any sequence of characters and '?' matches a single character. Click the eraser icon in the filter box to clear the filter.

To
save screen space, you can hide the Process Hierarchy Tree panel
and navigate the hierarchy using the breadcrumb bar. The breadcrumb
bar is turned on/off by the toolbar button
.

Click the arrow beside the breadcrumb item to show the hierarchy tree. The function table will be updated according to your selection.

All processes are contained in process groups, and all threads are contained in thread groups. These are meant as organizational tools that allow you to better analyze groups of processes and threads.
There are two or three pre-defined process groups: My Application, Other Processes and Idle Time (AIX only). By default each process contains a single thread group called Threads. To move processes or threads to another existing group select them, then right click and select Move To > Group Name. To move processes or threads to a new group select them, then right click it and select Move To > <new group>. A dialog will appear allowing you to enter the name of the new group. Alternatively you may also move processes and threads by dragging them and dropping them onto an existing group.
Custom filters
can be created to focus on modules or files you are interested in.
To create a filter click the toolbar button
to open the Hotspots Filters dialog.

Select one or more modules, or select one or more files, the tree will be filtered to show only processes and threads that match the selected modules or files. Use the Add... button to add modules or files that are not in the list. Deselect all the modules or files to disable the filter.
A label next to the Whole System node indicates when a filter is applied. Process and Thread group nodes will have a label that shows how many processes or threads have been hidden by the filter.
