Re-profiling an existing snapshot
If you have set up filtering and analysis for a profiling session and you want to re-use these settings in a new profiling session, for example to see whether changes you've made have the effect you're looking for, you can do so by using the Re-profile button on a snapshot's tab.
First load the snapshot you want to re-profile, then click the Re-profile button on the snapshot's tab to open the dialog which allows you to make last-minute changes to filters and analysis settings. The profiling session will create a new snapshot.
