rs.status()¶

Definition定义¶

rs.status()¶

Returns the replica set status from the point of view of the member where the method is run. This method provides a wrapper around the replSetGetStatus command.

This output reflects the current status of the replica set, using data derived from the heartbeat packets sent by the other members of the replica set.

Output¶

For an example and details on the output, see replSetGetStatus.

• Starting in MongoDB 4.2.1

  If you run mongo shell helper rs.status() (or the replSetGetStatus command) on a member during its initial sync (i.e. STARTUP2 state), the command returns replSetGetStatus.initialSyncStatus metrics.

  Once the member completes its initial sync, the replSetGetStatus.initialSyncStatus metrics becomes unavailable.

• In earlier versions (3.4.x-4.2.0)

  To return initial sync status information, you must the replSetGetStatus command with the initialSync: 1 option on a secondary member or a member in STARTUP2 state:

  db.adminCommand( { replSetGetStatus: 1, initialSync: 1 } )

  The replSetGetStatus.initialSyncStatus metrics remains available after the member completes its initial sync. That is, you can run the replSetGetStatus command with the initialSync: 1 on the secondary member to return its initial sync information.

  You cannot specify initialSync: 1 in the mongo shell helper rs.status().
