`replSetGetStatus` (database command数据库命令)

Definition定义

replSetGetStatus

~~The replSetGetStatus command returns the status of the replica set from the point of view of the server that processed the command. replSetGetStatus must be run on the admin database.~~replSetGetStatus命令从处理该命令的服务器的角度返回副本集的状态。replSetGetStatus必须在admin数据库上运行。

~~The mongod instance must be a replica set member for replSetGetStatus to return successfully.~~mongod实例必须是副本集成员，replSetGetStatus才能成功返回。

Data provided by this command derives from data included in heartbeats sent to the server by other members of the replica set. Because of the frequency of heartbeats, these data can be several seconds out of date.此命令提供的数据来源于副本集其他成员发送到服务器的心跳中包含的数据。由于心跳的频率，这些数据可能会过时几秒钟。

Tip

~~In mongosh, this command can also be run through the rs.status() helper method.~~在mongosh中，此命令也可以通过rs.status()辅助方法运行。

~~Helper methods are convenient for mongosh users, but they may not return the same level of information as database commands.~~ 助手方法对mongosh用户来说很方便，但它们可能不会返回与数据库命令相同级别的信息。~~In cases where the convenience is not needed or the additional return fields are required, use the database command.~~如果不需要便利性或需要额外的返回字段，请使用database命令。

Compatibility兼容性

~~This command is available in deployments hosted in the following environments:~~此命令在以下环境中托管的部署中可用：

MongoDB Atlas~~: The fully managed service for MongoDB deployments in the cloud~~：云中MongoDB部署的完全托管服务

Important

~~This command is not supported in M0 and Flex clusters. For more information, see Unsupported Commands.~~M0和Flex集群不支持此命令。有关详细信息，请参阅不支持的命令。

MongoDB Enterprise~~: The subscription-based, self-managed version of MongoDB~~：MongoDB的基于订阅的自我管理版本
MongoDB Community~~: The source-available, free-to-use, and self-managed version of MongoDB~~：MongoDB的源代码可用、免费使用和自我管理版本

Syntax语法

~~The command has the following syntax:~~该命令具有以下语法：

db.adminCommand(
   {
     replSetGetStatus: 1
   }
)

~~If you run replSetGetStatus or the mongosh helper rs.status() 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replSetGetStatus或mongosh辅助程序rs.status()，则该命令将返回replSetGetStatus.initialSyncStatus度量。

~~After the member completes the initial synchronization and transitions to another state, the replSetGetStatus.initialSyncStatus metrics are no longer available.~~在成员完成初始同步并转换到另一个状态后，replSetGetStatus.initialSyncStatus初始同步状态度量不再可用。

Note

~~If you haven't yet initialized your replica set, the replSetGetStatus command returns the following error:~~如果您尚未初始化副本集，initialized命令将返回以下错误：

MongoServerError: no replset config has been received

~~Run the replSetInitiate command and try again.~~运行replSetInitiate命令，然后重试。

Example示例

Primary

~~The following example runs the replSetGetStatus command on the admin database of the replica set primary:~~以下示例在复制集主的admin数据库上运行replSetGetStatus命令：

db.adminCommand( { replSetGetStatus: 1 } )

~~The command returns the following output for an example replica set primary:~~该命令为示例副本集主返回以下输出：

~~In earlier versions (3.6.x-4.2.0)~~在早期版本（3.6x-4.2.0）中

~~You can include the optional initialSync: 1 to include the replSetGetStatus.initialSyncStatus in the output (you can omit if you do not want to return the initial sync status):~~您可以包含可选的initialSync:1，以在输出中包含replSetGetStatus.initialSyncStatus（如果不想返回初始同步状态，可以省略）：

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

Include Intial Sync Metrics

~~Starting in MongoDB 5.2,~~从MongoDB 5.2开始，: ~~the replSetGetStatus.initialSyncStatus document contains additional fields when using a file copy based initial sync.~~使用基于文件副本的初始同步时，replSetGetStatus.initialSyncStatus文档包含其他字段。

~~If you run replSetGetStatus on a member during its initial sync, the command returns replSetGetStatus.initialSyncStatus metrics.~~如果在成员的初始同步期间对其运行replSetGetStatus，则该命令将返回replSetGetStatus.initialSyncStatus度量。

db.adminCommand( { replSetGetStatus: 1 } )

~~The following example runs the replSetGetStatus command on the admin database of the 4.4 replica set member during its initial sync:~~以下示例在4.4副本集成员的admin数据库的初始同步期间运行replSetGetStatus命令：
