In the previous recipe, we saw how to view some important statistics of a collection from an administrative perspective. In this recipe, we get an even higher picture, getting those (or most of those) statistics at the database level.
To find the stats of the database, we need to have a server up and running and a single node is what should be okay. Refer to the recipe Installing single node MongoDB in Chapter 1, Installing and Starting the Server for information on how to start the server. The data on which we would be operating needs to be imported in the database. The steps to import the data are given in the recipe Creating Test Data in Chapter 2, Command-line Operations and Indexes. Once these steps are completed, we are all set to go ahead with this recipe. Refer to the previous recipe if you need to see how to view stats at the collection level.
