Field Description
hosts[] object

List of hosts for the cluster.
hosts[].
name		 string

Name of the Redis host. The host name is assigned by MDB at creation time, and cannot be changed. 1-63 characters long.

The name is unique across all MDB hosts that exist on the platform, as it defines the FQDN of the host.
hosts[].
clusterId		 string

ID of the Redis cluster. The ID is assigned by MDB at creation time.
hosts[].
zoneId		 string

ID of the availability zone where the Redis host resides.
hosts[].
subnetId		 string

ID of the subnet that the host belongs to.
hosts[].
resources		 object

Resources allocated to the Redis host.
hosts[].
resources.
resourcePresetId		 string

ID of the preset for computational resources available to a host (CPU, memory etc.). All available presets are listed in the documentation.
hosts[].
resources.
diskSize		 string (int64)

Volume of the storage available to a host, in bytes.
hosts[].
resources.
diskTypeId		 string

Type of the storage environment for the host. Possible values:

  • network-ssd - network SSD drive,
  • local-ssd - local SSD storage.
hosts[].
role		 string

Role of the host in the cluster.

  • ROLE_UNKNOWN: Role of the host in the cluster is unknown.
  • MASTER: Host is the master Redis server in the cluster.
  • REPLICA: Host is a replica (standby) Redis server in the cluster.
hosts[].
health		 string

Status code of the aggregated health of the host.

  • HEALTH_UNKNOWN: Health of the host is unknown.
  • ALIVE: The host is performing all its functions normally.
  • DEAD: The host is inoperable, and cannot perform any of its essential functions.
  • DEGRADED: The host is degraded, and can perform only some of its essential functions.
hosts[].
services[]		 object

Services provided by the host.
hosts[].
services[].
type		 string

Type of the service provided by the host.

  • REDIS: The host is a Redis server.
  • ARBITER: The host provides a Sentinel-only service (a quorum node).
  • REDIS_CLUSTER: The host is a Redis Cluster node.
hosts[].
services[].
health		 string

Status code of server availability.

  • HEALTH_UNKNOWN: Health of the server is unknown.
  • ALIVE: The server is working normally.
  • DEAD: The server is dead or unresponsive.
hosts[].
shardName		 string
hosts[].
replicaPriority		 integer (int64)

A replica with a low priority number is considered better for promotion. A replica with priority of 0 will never be selected by Redis Sentinel for promotion. Works only for non-sharded clusters. Default value is 100.
hosts[].
assignPublicIp		 boolean (boolean)

Flag showing public IP assignment status to this host.
nextPageToken string

This token allows you to get the next page of results for list requests. If the number of results is larger than pageSize, use the nextPageToken as the value for the pageToken query parameter in the next list request. Each subsequent list request will have its own nextPageToken to continue paging through the results.
