Response Parameters

Name Type Description
clusterName string Display name of the cluster. Note that mongod itself doesn’t allow you to name a cluster; Ops Manager supplies this name and you can update it. For a replica set within a sharded cluster, the cluster name is the name of its parent cluster.
groupId string Unique identifier of the project to which the cluster belongs.
id string Unique identifier of the cluster.
lastHeartbeat date Timestamp in ISO 8601 date and time format in UTC when Ops Manager most recently processed a ping from this cluster.
replicaSetName string Replica set name. Ops Manager returns this value when a cluster has a typeName of REPLICA_SET or CONFIG_SERVER_REPLICA_SET.
shardName string Shard name. Ops Manager returns this value when a cluster has a typeName of SHARDED or a REPLICA_SET that part of a sharded cluster.
typeName string

Cluster type. Ops Manager may return:

typeName Description
REPLICA_SET A replica set.
SHARDED A sharded cluster where each shard is a standalone instance. No shards are replica sets.
SHARDED_REPLICA_SET A sharded cluster that contains at least one shard that is a replica set.
CONFIG_SERVER_REPLICA_SET Config servers deployed as a replica set.
