setVerboseShell()¶

The setVerboseShell() method configures the mongo shell to print the duration of each operation.

setVerboseShell() has the form:

setVerboseShell(true)

setVerboseShell() takes one boolean parameter. Specify true or leave the parameter blank to activate the verbose shell. Specify false to deactivate.

Example¶

The following example demonstrates the behavior of the verbose shell:

From the mongo shell, set verbose shell to true:
```
setVerboseShell(true)
```

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

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

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

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