You can call the DescribeDBInstanceNetInfo operation to query all the endpoints of an ApsaraDB RDS instance.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes DescribeDBInstanceNetInfo

The operation that you want to perform. Set the value to DescribeDBInstanceNetInfo.

DBInstanceId String Yes rm-uf6wjk5xxxxxxx

The ID of the instance.
ClientToken String No ETnLKlblzczshOTUbOCzxxxxxxxxxx

The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must ensure that it is unique among different requests. The token can only contain ASCII characters and cannot exceed 64 characters in length.

Flag String No N/A

A hidden parameter.
DBInstanceNetRWSplitType String No Normal

The type of endpoint to query. Valid values:

  • Normal
  • ReadWriteSplitting
Note The system returns both types of endpoints by default.

Response parameters

Parameter Type Example Description
DBInstanceNetInfos Array

An array that consists of endpoints.
DBInstanceNetInfo
ConnectionString String rm-uf6wxxxxx.mysql.rds.aliyuncs.com

The endpoint that is used to connect to the instance.
IPAddress String 192.168.12.84

The IP address that is associated with the endpoint.
IPType String Public

The network type of the instance. Valid values:

  • If the instance resides in the classic network:
    • Inner: internal network
    • Public: Internet
  • If the instance resides in a virtual private cloud (VPC):
    • Private: internal network
    • Public: Internet
Port String 3306

The port that is associated with the endpoint.
VPCId String vpc-uf6f7l4fg90xxxxxxxxxx

The ID of the VPC to which the instance belongs.
VSwitchId String vsw-uf6adz52c2pxxxxxxxxxx

The ID of the vSwitch associated with the specified VPC.
ConnectionStringType String Normal

The type of the endpoint. Valid values:

  • Normal
  • ReadWriteSplitting
MaxDelayTime String 12

The threshold of latency that is allowed on the read-only instances. Unit: seconds. This parameter is returned only for the read/write splitting endpoint.

Note If the latency on a read-only instance exceeds the specified threshold, ApsaraDB RDS no longer routes read requests to the read-only instance.
DistributionType String Standard

The policy that is used to allocate read weights. This parameter is returned only for a read/write splitting endpoint. Valid values:

  • Standard: ApsaraDB RDS automatically allocates a read weight to each instance based on the instance specifications.
  • Custom: You must manually allocate a read weight to each instance.
DBInstanceWeights Array

An array that consists of read weights. This parameter is returned only when the read/write splitting function is enabled for the instance.

DBInstanceWeight
DBInstanceId String rm-uf6wjk5xxxxxxx

The ID of the instance.
DBInstanceType String Master

The role of the instance. Valid values:

  • Master: primary
  • Readonly: read-only
Weight String 100

The read weight of the instance.
Availability String Unavailable

The availability of the instance. Valid values:

  • Unavailable
  • Available
ExpiredTime String 1209534

The remaining time of the instance in the classic network if the instance is connected in hybrid access mode. Unit: seconds.

SecurityIPGroups Array

An array that consists of IP address whitelists.
securityIPGroup
SecurityIPGroupName String Default

The name of the IP address whitelist.
SecurityIPs String 127.0.0.1

An array that consists of IP addresses in the IP address whitelist.
Upgradeable String Disabled

Indicates whether the IP version can be updated. Valid values: Enable and Disabled.

Note The IP version can be updated from IPv4 to IPv6.
InstanceNetworkType String VPC

The network type of the instance. Valid values:

  • Classic
  • VPC
RequestId String 777C4593-8053-427B-99E2-105593277CAB

The ID of the request.
SecurityIPMode String safety

The whitelist mode of the instance. Valid values:

  • normal: standard whitelist mode
  • safety: enhanced whitelist mode
