Using the Filter Data dialog box, you can limit the information that is displayed by
specifying the experiments, samples,
threads, LWPs, and CPUs for which to display metrics; or by specifying a filter expression. Each experiment can have its own
selection
of samples, thread, LWPs, and CPUs, or its own filter expression. Filtering by thread and by sample does not apply to the data
in the Timeline tab.
Simple Tab
In the Simple tab, you can select
the experiments for which you want to filter data. You can then specify the samples,
threads, LWPs, and CPUs for which to display metrics, or use the Advanced tab to specify a
filter expression.
- Experiments List. Lists the open experiments. Click an experiment to select it. Selected
experiments are highlighted.
Enabled experiments are checked. The checkboxes are not active.
- Select All button. Selects all experiments in the list.
- Clear All button. Deselects all experiments in the list.
- Reverse button. Selects all unselected experiments and deselects all selected experiments.
- Enable All button. Enables data display for all experiments in the list.
- Enable Selected button. Enables data display for the selected experiments.
- Disable All button. Disables data display for all experimens in the list.
- Disable Selected button. Disables data display for the selected experiments.
- Samples, Threads, LWPs, CPUs. Let you specify the samples,
threads, LWPs, and CPUs for which you want to display data. In each text box,
you can type a
list that includes single numbers or ranges such as 5-9, separated by commas.
Or you can click the Select All button to enter the full range into the text box. The available range is shown
under each text box.
Advanced Tab
In this tab, you can specify a filter expression that evaluates as true for any data
record you want to include in the display.
- Filter Clause text box. If you type a filter clause, operands can be either
constants or fields within a data record. You can use arithmetic operators and logical
operators in C notation. An expression can include blanks.
If you have selected one or more items in the Function tab,
DataObjects tab, DataLayout tab, or a MemoryObject tab, click the Compose Filter Clause
button in the toolbar to load the text box with a clause
that reflects the
selection.
- AND button. Click this button to append the clause in the Filter Clause text box to the
expression in the Specify filter text field with an AND operand.
- OR button. Click this button to append the clause in the Filter Clause text box to the
expression in the Specify filter text field with an OR operand.
- Set button. Click this button to set the filter expression to the clause in the
Filter Clause text box.
- Specify filter text field. Displays the current filter expression.
Apply the filters to the data by clicking the Apply button.
If you do not apply the selections, they revert to the default when another experiment selection is made.

You can repeat this procedure for different experiment
selections.

|
If you include an experiment that you have already
filtered in another selection, the filters in the second
selection override the first.
