Filtering Latency Event Information

Filtering Latency Event Information

When making a latency recording with a low latency threshold or making a recording that runs for long time, several million events can occur. Often, this can exceed what Mission Control is able to handle, usually because the computer doesn't have enough memory or because it takes too much time to process all the events in the user interface. To prevent problems from occurring because of too many events being recorded, Mission Control allows you to filter out the following types of events:

Events that were shorter than a certain threshold set in the recording loading wizard.
Events in a certain time interval; for example, all events from 10 to 30 seconds.
Events that belongs to certain thread. You can select a set of threads in a list box.
Events of a certain event type.
Events randomly given a certain probability.

To filter latency event information

When you are creating your recording and an excessive amount of events occur, the Open JRA Recording dialog box appears (Figure 16-27).

Select the criteria by which you want to filter the events and click Continue.
