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.从运行该方法的成员的角度返回副本集状态。

Important

mongosh Method

This page documents a mongosh method. This is not the documentation for database commands or language-specific drivers, such as Node.js.

For the database command, see the replSetGetStatus command.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

For the legacy mongo shell documentation, refer to the documentation for the corresponding MongoDB Server release:

mongo shell v4.4

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.此输出使用从副本集的其他成员发送的检测信号数据包派生的数据来反映副本集的当前状态。

Output输出

For an example and details on the output, see replSetGetStatus.有关输出的示例和详细信息，请参阅replSetGetStatus。

• Starting in MongoDB 4.2.1从MongoDB 4.2.1开始

  If you run the mongosh helper method rs.status() (or the replSetGetStatus command) on a member during its initial sync (i.e. STARTUP2 state), the command returns replSetGetStatus.initialSyncStatus metrics.如果在成员的初始同步（即STARTUP2状态）期间对其运行mongosh助手方法rs.status()（或replSetGetStatus命令），则该命令将返回replSetGetStatus.initialSyncStatus度量。

  Once the member completes its initial sync, the replSetGetStatus.initialSyncStatus metrics becomes unavailable.一旦成员完成初始同步，replSetGetStatus.initialSyncStatus度量将不可用。

• In earlier versions (3.4.x-4.2.0)在早期版本中（3.4x-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:要返回初始同步状态信息，必须在辅助成员或STARTUP2状态的成员上使用带有initialSync:1选项的replSetGetStatus命令：

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

  The replSetGetStatus.initialSyncStatus metrics remains available after the member completes its initial sync. 成员完成初始同步后，replSetGetStatus.initialSyncStatus度量仍然可用。That is, you can run the replSetGetStatus command with the initialSync: 1 on the secondary member to return its initial sync information.也就是说，您可以在辅助成员上使用initialSync:1运行replSetGetStatus命令，以返回其初始同步信息。

  You cannot specify initialSync: 1 to the mongosh helper method rs.status().不能将initialSync:1指定给mongosh助手方法rs.status()。
