Click on the Book icon to the left of the desired Package. You will be brought to the Package's History screen. On the left side of the page you'll see a listing of each time that package was run (including the current run if it's actively running when you're there). For each package run, you will see:

The Details window will give you specific configuration information of the settings that were chosen when the package was run.
The Log window will provide a step-by-step chronology of the Activities that ran as part of the package.
