Ever wanted to collection data for the last x seconds/minutes of your application's execution so that you didn't have tons of data to sift through?! Well, now you can do exactly that with the VTune Amplifier XE 2017 beta software.
From the command line, use the ring-buffer option. From the graphical user interface, use the Limit collected data by option in the Advanced section of the Analysis Target tab.
See the "Setting the Analysis Timer for the Last Seconds of Collection" section of the "Limiting Data Collection" help topic for command line usage or the "Data Collection Limit" for the graphical user interface option.
