MongoDB Package Components

Core Processes

The core components in the MongoDB package are: mongod, the core database process; mongos the controller and query router for sharded clusters; and mongo the interactive MongoDB Shell.

Windows Services

The mongod.exe and mongos.exe describe the options available for configuring MongoDB when running as a Windows Service. The mongod.exe and mongos.exe binaries provide a superset of the mongod and mongos options.

Binary Import and Export Tools

mongodump provides a method for creating BSON dump files from the mongod instances, while mongorestore makes it possible to restore these dumps. bsondump converts BSON dump files into JSON.

Deprecated since version 3.2: mongooplog

Data Import and Export Tools

mongoimport provides a method for taking data in JSON, CSV, or TSV and importing it into a mongod instance. mongoexport provides a method to export data from a mongod instance into JSON, CSV, or TSV.

Note

The conversion between BSON and other formats lacks full type fidelity. Therefore you cannot use mongoimport and mongoexport for round-trip import and export operations.

Diagnostic Tools

mongostat, mongotop, and mongosniff provide diagnostic information related to the current operation of a mongod instance.

Note

Because mongosniff depends on libpcap, most distributions of MongoDB do not include mongosniff.

GridFS

mongofiles provides a command-line interact to a MongoDB GridFS storage system.
