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命令从处理该命令的服务器的角度返回副本集的状态。replSetGetStatus must be run against the admin database.必须针对admin数据库运行。

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

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 此命令提供的数据来自副本集其他成员发送到服务器的心跳中包含的数据。Because of the frequency of heartbeats, these data can be several seconds out of date.由于心跳的频率，这些数据可能会过时几秒。

Syntax语法

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

db.adminCommand( { replSetGetStatus: 1 } )

Example示例

The following example runs the replSetGetStatus command on the admin database of the replica set primary:以下示例在副本集主数据库的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:该命令返回示例副本集主副本的以下输出：

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 } )
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.当使用基于文件副本的初始同步时，replSetGetStatus.initialSyncStatus文档包含其他字段。
Starting in MongoDB 4.2.1,从MongoDB 4.2.1开始，

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 } )

Once the member finishes its initial sync and transitions to another state, the replSetGetStatus.initialSyncStatus document is no longer available.一旦成员完成初始同步并转换到另一个状态，replSetGetStatus.initialSyncStatus文档将不再可用。

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 } )

For 3.6.x-4.2.0 replica sets, replSetGetStatus.initialSyncStatus metrics remains available after the member completes its initial sync. 对于3.6x-4.2.0副本集，在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，可以在辅助成员上运行带有initialSync:1的replSetGetStatus命令，以返回其初始同步信息。

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副本集成员的初始同步期间对其admin数据库运行replSetGetStatus命令：

Important重要
Availability可利用性

Starting in MongoDB 4.2.1, replSetGetStatus.initialSyncStatus metrics are only available when run on a member during its initial sync (i.e. STARTUP2 state).从MongoDB 4.2.1开始，replSetGetStatus.initialSyncStatus度量仅在成员初始同步期间（即STARTUP2状态）运行时可用。

In earlier versions (3.6.x-4.2.0), replSetGetStatus.initialSyncStatus metrics are available when the command is run with initialSync: 1 option on a secondary or a member in its STARTUP2 state, even after the member completes its initial sync. 在早期版本（3.6x-4.2.0）中，当命令在辅助或处于STARTUP2状态的成员上使用initialSync:1选项运行时，即使在该成员完成初始同步后，replSetGetStatus.initialSyncStatus度量也可用。However, some fields that relate to the progress of an on-going initial sync only appear while the initial sync is in progress and do not appear once the initial sync completes.然而，一些与正在进行的初始同步的进度相关的字段仅在初始同步进行时出现，而在初始同步完成后不会出现。

The start timestamp of the initial sync for this member.此成员的初始同步的开始时间戳。

replSetGetStatus.initialSyncStatus.initialSyncEnd

The end timestamp of the initial sync for this member.此成员的初始同步的结束时间戳。

replSetGetStatus.initialSyncStatus.initialSyncElapsedMillis

The number of milliseconds between initialSyncStart and initialSyncEnd.initialSyncStart和initialSyncEnd之间的毫秒数。

replSetGetStatus.initialSyncStatus.initialSyncAttempts

Array of documents where each document corresponds to a single initial sync attempt. 文档数组，其中每个文档对应于一次初始同步尝试。For Example:例如：

"initialSyncAttempts" : [
   {
      "durationMillis" : 59539,
      "status" : "InvalidOptions: error fetching oplog during initial sync :: caused by :: Error while getting the next batch in the oplog fetcher :: caused by :: readConcern afterClusterTime value must not be greater than the current clusterTime. Requested clusterTime: { ts: Timestamp(0, 1) }; current clusterTime: { ts: Timestamp(0, 0) }",
      "syncSource" : "m1.example.net:27017",
      "rollBackId" : 1,
                     // Available starting in v4.4

            // Available starting in v4.4
      "totalTimeUnreachableMillis" : 52601  // Available starting in v4.4
   }
],
