Example

The following example demonstrates the behavior of the verbose shell:

1. From the mongo shell, set verbose shell to true:

   copy

   setVerboseShell(true)
   

2. With verbose shell set to true, run db.collection.aggregate():

   copy

   db.restaurants.aggregate(
      [
         { $match: { "borough": "Queens", "cuisine": "Brazilian" } },
         { $group: { "_id": "$address.zipcode" , "count": { $sum: 1 } } }
      ]
   );
   

3. In addition to returning the results of the operation, the mongo shell now displays information about the duration of the operation:

   copy

   { "_id" : "11377", "count" : 1 }
   { "_id" : "11368", "count" : 1 }
   { "_id" : "11101", "count" : 2 }
   { "_id" : "11106", "count" : 3 }
   { "_id" : "11103", "count" : 1 }
