  • 例子

注意

此处列出的原生方法适用于旧版 mongo Shell。

要使用 mongosh中的原生方法，请参阅mongosh中的原生方法。

setVerboseShell()

The setVerboseShell() method configures mongosh 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.

例子

The following example demonstrates the behavior of the verbose shell:

  1. From mongosh, set verbose shell to true:

    setVerboseShell(true)

  2. 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 } } }
       ]
    );

  3. In addition to returning the results of the operation, mongosh 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 }
