replSetGetStatus（数据库命令）

定义

replSetGetStatus

replSetGetStatus 命令从处理该命令的服务器的角度返回副本集的状态。在管理员数据库上运行 replSetGetStatus。

The mongod instance must be a replica set member for replSetGetStatus to return successfully.

此命令的数据来源于其他副本集成员发送的心跳。由于心跳频率，这些数据可能会过时几秒。

提示

In mongosh, this command can also be run through the rs.status() helper method.

Helper methods are convenient for mongosh users, but they may not return the same level of information as database commands. In cases where the convenience is not needed or the additional return fields are required, use the database command.

兼容性

此命令可用于以下环境中托管的部署：

MongoDB Atlas：用于云中 MongoDB 部署的完全托管服务

重要

M0 和 Flex 集群不支持此命令。有关更多信息，请参阅不支持的命令。

MongoDB Enterprise：基于订阅、自我管理的 MongoDB 版本
MongoDB Community：源代码可用、免费使用且可自行管理的 MongoDB 版本

语法

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 in the STARTUP2 state, the command returns replSetGetStatus.initialSyncStatus metrics.

After the member completes the initial synchronization and transitions to another state, the replSetGetStatus.initialSyncStatus metrics are no longer available.

注意

如果尚未initialized副本集， replSetGetStatus命令将返回以下错误：

MongoServerError: no replset config has been received

运行replSetInitiate命令并重试。

例子

The following example runs the replSetGetStatus command on the admin database of the replica set primary:

db.adminCommand( { replSetGetStatus: 1 } )

此命令将返回一个示例副本集主节点的如下输出：

The following example runs the replSetGetStatus command on the admin database of the replica set secondary:

在早期版本（3.4.x-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):

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

从 MongoDB 5.2 开始，: the replSetGetStatus.initialSyncStatus document contains additional fields when using a file copy based initial sync.

If you run replSetGetStatus on a member during its initial sync, the command returns replSetGetStatus.initialSyncStatus metrics.

db.adminCommand( { replSetGetStatus: 1 } )

After the member completes the initial synchronization and transitions to another state, the replSetGetStatus.initialSyncStatus metrics are no longer available.

ts，操作的时间戳。
t, the term in which the operation was originally generated on the primary.

replSetGetStatus.optimes.lastCommittedOpTime: 从该成员的角度来看，有关最近一次写入大多数副本集成员的操作的信息。

replSetGetStatus.optimes.lastCommittedWallTime: The ISODate-formatted date string corresponding to lastCommittedOpTime.

replSetGetStatus.optimes.readConcernMajorityOpTime: Information, from the viewpoint of this member, regarding the most recent operation that can fulfill read concern "majority" queries. That is, the most recent lastCommittedOpTime that can fulfill "majority" queries. readConcernMajorityOpTime is either less than or equal to lastCommittedOpTime.

replSetGetStatus.optimes.appliedOpTime: 从该成员的角度来看，有关最近一次应用于该副本集成员的操作的信息。

replSetGetStatus.optimes.lastAppliedWallTime: The ISODate-formatted date string corresponding to appliedOpTime.

replSetGetStatus.optimes.durableOpTime: 从该成员的角度来看，有关最近一次写入该副本集成员日志的操作的信息。

replSetGetStatus.optimes.lastDurableWallTime: The ISODate-formatted date string corresponding to durableOpTime.

replSetGetStatus.optimes.lastWrittenWallTime: 写入该成员 oplog 的最新条目的 ISODate 格式日期字符串。
8.0版本新增。

replSetGetStatus.optimes.writtenOpTime: 写入该成员 oplog 的最新条目的 optime。
8.0版本新增。

replSetGetStatus.lastStableRecoveryTimestamp: 仅供内部使用

replSetGetStatus.electionCandidateMetrics

Metrics related to the election of the current primary. electionCandidateMetrics is only available on the primary or a candidate for election. For a candidate, the metrics are unavailable after the candidate loses the election.

replSetGetStatus.electionCandidateMetrics.lastElectionReason: 成员宣布选举的原因。

replSetGetStatus.electionCandidateMetrics.lastElectionDate: 该成员发起选举的日期和时间。

replSetGetStatus.electionCandidateMetrics.electionTerm: The member's election count (that is, term) at the time it called the new election.

replSetGetStatus.electionCandidateMetrics.lastCommittedOpTimeAtElection: The most recent majority-committed optime, as seen by this member, at the time it called the new election.

replSetGetStatus.electionCandidateMetrics.lastSeenOpTimeAtElection: The member's most recent applied optime at the time it called the new election.

replSetGetStatus.electionCandidateMetrics.lastSeenWrittenOpTimeAtElection: 在调用新选举时，写入该节点的 oplog 的最新条目的 optime 。
8.0版本新增。

replSetGetStatus.electionCandidateMetrics.numVotesNeeded: 赢得选举所需的票数。

replSetGetStatus.electionCandidateMetrics.priorityAtElection: 宣布选举时该成员的priority。

replSetGetStatus.electionCandidateMetrics.electionTimeoutMillis: 选举时副本集已配置的 electionTimeoutMillis 设置。

replSetGetStatus.electionCandidateMetrics.priorPrimaryMemberId: 上一个主节点的 members[n]._id。如果没有以前的主节点，则该字段不存在。

replSetGetStatus.electionCandidateMetrics.targetCatchupOpTime: 新当选的主节点的目标 ops/sec 用于其追赶过程。只有当新当选的主节点达到目标追赶 ops/sec 时，它才能开始接受写入。

replSetGetStatus.electionCandidateMetrics.numCatchUpOps: 新当选的主节点在成功结束追赶过程时所应用的操作数量。

replSetGetStatus.electionCandidateMetrics.newTermStartDate: 成员作为主节点的时段开始的日期和时间（即 new term 条目写入 oplog 的日期和时间）。

replSetGetStatus.electionCandidateMetrics.wMajorityWriteAvailabilityDate: 在副本集选举后，写关注 "majority" 可用的日期和时间（new term oplog 条目被多数提交的日期和时间）。

replSetGetStatus.electionParticipantMetrics

与节点参与的最近一次选举相关的指标。

replSetGetStatus.electionParticipantMetrics.votedForCandidate: 布尔值，表示该节点是否投票支持召集选举的候选节点。

replSetGetStatus.electionParticipantMetrics.electionTerm: 成员所参与选举的任期。该任期可标识与参与者指标关联的选举。

replSetGetStatus.electionParticipantMetrics.lastVoteDate: 记录参与者投票时间的 ISODate 格式的日期字符串。

replSetGetStatus.electionParticipantMetrics.electionCandidateMemberId: 召集选举的候选节点的 members[n]._id。

replSetGetStatus.electionParticipantMetrics.voteReason: 如果该成员未投票给候选节点，那么投票的原因是什么。如果该成员投票给候选节点，则该值为空字符串。

replSetGetStatus.electionParticipantMetrics.lastAppliedOpTimeAtElection

该成员在上次选举时最近一次应用的 optime。

ops/sec 值是一个包含时间戳 (ts) 和任期 (t) 的文档。

replSetGetStatus.electionParticipantMetrics.lastWrittenOpTimeAtElection: 在上次选举时写入此节点的 oplog 的最新条目的 optime。

8.0版本新增。

replSetGetStatus.electionParticipantMetrics.priorityAtElection: 选举时该成员的 priority。

replSetGetStatus.electionParticipantMetrics.newTermStartDate

当选的主节点任期的开始日期和时间；这对应于主节点将 new term 条目写入其 oplog 的时间，而不是该条目被添加（即复制）到从节点的 oplog 的时间。

The field is available for secondary members only. For the primary, see replSetGetStatus.electionCandidateMetrics.newTermStartDate instead.

replSetGetStatus.electionParticipantMetrics.newTermAppliedDate

此从节点应用 new term 条目的日期和时间。

replSetGetStatus.members[n].ip: The resolved IP address of the member. If the mongod is unable to resolve the replSetGetStatus.members[n].name to an IP address, the return value is a BSON null. Otherwise, the returned value is a string representation of the resolved IP address.

replSetGetStatus.members[n].self

布尔值，表示该成员是否为当前 mongod 实例。

self字段仅包含在当前mongod实例的文档中，因此其值始终为 true。
