db.printShardingStatus()

Prints a formatted report of the sharding configuration and the information regarding existing chunks in a sharded cluster.

Only use db.printShardingStatus() when connected to a mongos instance.

The db.printShardingStatus() method has the following parameter:

Parameter
Type
Description
verbose
boolean

Optional. Determines the level of verbosity.

If true, the method displays:

  • Full details of the chunk distribution across shards even if you have 20 or more chunks, as well as the number of chunks on each shard.
  • Details of active mongos instances.

If false, the method displays:

  • Full details of the chunk distribution across shards only if you have less than 20 chunks. If you have 20 or more chunks, the method instead returns a too many chunks to print ... message, showing only the number of chunks on each shard.
  • Only the version and number of active mongos instances.

The default verbose value is false.

See sh.status() for details of the output.

Note

The db.printShardingStatus() method run in the mongo shell does not return JSON. Use db.printShardingStatus() for manual inspection, and Config Database in scripts.
