Queries the endpoints of an ApsaraDB for 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

ConnectionString String rm-uf6wxxxxx.mysql.rds.aliyuncs.com

The endpoint of the instance.
IPAddress String 192.168.12.84

The IP address associated with the endpoint.
IPType String Public

The network type of the endpoint. Valid values:

  • If the instance resides in a classic network:
    • Inner: The endpoint is an internal endpoint.

The type of the endpoint. Valid values:

  • Normal
  • ReadWriteSplitting
MaxDelayTime String 12

The latency threshold that is allowed by the endpoint. This parameter is returned only for a read/write splitting endpoint. Unit: seconds.

Note If the latency on a read-only instance exceeds the specified threshold, the system 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: The system automatically allocates a read weight to each instance based on the instance specifications.
  • Custom: You must manually allocate a read weight to each instance.

SecurityIPGroupName String Default

The name of the IP address whitelist.
SecurityIPs String 127.0.0.1

The IP addresses in the IP address whitelist.
DBInstanceWeights Array

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

DBInstanceId String rm-uf6wjk5xxxxxxx

The ID of the instance.
DBInstanceType String Master

The role of the instance. Valid values:

  • Master: The instance is a primary instance.
  • Readonly: The instance is a read-only instance.
