The dashboard is an overview of all of the products within an account, and shows a number of graphs that show detailed information about products.
The schema graphs show an overview of each schema, products that are held within those schemas and the lifecycle stages of those products.
The channel coverage graphs show information relating to which products are released to which channels. These show how many products are released to the channel, how many are unreleased and how many products are incomplete to be released to the channel.
The feed coverage graphs show products that have been created by feeds. In the above example, the FTP feed is the only feed that has created products, and has only created one product in the example account.
The dashboard updates at set intervals throughout the day, however selecting 'Collect now' in the top right of the dashboard will update the information immediately.
