MongoDB Package Components¶
On this page
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.
