Querying Details of Shards

Function

This API is used to query shards and replicas of cluster instances.

URI

GET /v2/{project_id}/instance/{instance_id}/groups

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID.
instance_id	Yes	String	Instance ID.

Request Parameters

None

Response Parameters

Status code: 200

**Table 2** Response body parameters
Parameter	Type	Description
group_list	Array of InstanceGroupListInfo objects	Shard list.
group_count	Integer	Total number of shards in the instance.

**Table 3** InstanceGroupListInfo
Parameter	Type	Description
group_id	String	Shard ID.
group_name	String	Shard name.
replication_list	Array of InstanceReplicationListInfo objects	List of replicas in the shard.

**Table 4** InstanceReplicationListInfo
Parameter	Type	Description
replication_role	String	Role of the replica. Options: master: master slave: replica
replication_ip	String	Replica IP address.
is_replication	Boolean	Whether the replica is a newly added one.
replication_id	String	Replica ID.
node_id	String	Node ID.
status	String	Replica status. Enumeration values: Active Inactive
az_code	String	AZ where the replica is in.
dimensions	Array of InstanceReplicationDimensionsInfo objects	Monitoring metric dimension of the replica used to call the Cloud Eye API for querying monitoring metrics. Replica monitoring is multi-dimensional. The returned array contains information about two dimensions. When querying monitoring data from Cloud Eye, transfer parameters of multiple dimensions to obtain the metric data. The first dimension is the primary dimension of the replica. The dimension name is dcs_instance_id, and the dimension value corresponds to the ID of the instance to which the replica belongs. The name of the second dimension is dcs_cluster_redis_node, and the dimension value is the monitored object ID of the replica, which is different from the replica ID or node ID.

**Table 5** InstanceReplicationDimensionsInfo
Parameter	Type	Description
name	String	Monitoring dimension name.
value	String	Dimension value.

Status code: 500

**Table 6** Response body parameters
Parameter	Type	Description
error_msg	String	Error message. Maximum: 1024
error_code	String	Error code. Maximum: 9
error_ext_msg	String	Extended error information. This parameter is not used currently and is set to null. Maximum: 1024

Status code: 400

**Table 7** Response body parameters
Parameter	Type	Description
error_msg	String	Error message. Maximum: 1024
error_code	String	Error code. Maximum: 9
error_ext_msg	String	Extended error information. This parameter is not used currently and is set to null. Maximum: 1024
