In the second part of the dashboard, you will see on your left your top 5 campaigns activity, by campaign ID, name, impressions, clicks, conversions, eCPA and cost. On your right you can see your top 5 creative activity.
The total impressions and budget spent are only for the selected timeframe.
You can always click on the magnifying glass next to each campaign or creative to go directly to the report page.
If you click on the campaign name you will go to that campaign set up page, same for creative.
