Setting Trace Filter

Using filters is a great way to minimize the amount of data that is shown in the Latency Traces table. The available trace filter is quite powerful with capabilities to filter on packages, classes, and methods. You can create your own filter profile.

The Latency Traces tab has a powerful filtering function that allows you to easily filter out packages, classes, and methods from the Latency Traces table. That way you will get a better overview of the exact methods you want to study. You can also decide if you want to show or hide the stack frames that matches the filter.

To add a package, class, or method

Click the Trace filters button.

The Trace filters window opens (Figure 19-2).
