This topic lists the common parameters of Application Real-Time Monitoring Service (ARMS) API operations and ARMS endpoints.

Note The POP gateway provides services by using the Internet. If you cannot use the Internet, you cannot access the services.

Common request parameters

Parameter Description
region The region of the API gateway. For information about supported regions, see Endpoints.
  • If you use an Alibaba Cloud account or a RAM user to call an API operation, this parameter is the AccessKey pair of the account.
  • If you use a RAM role to call an API operation, this parameter is the AccessKey pair in the Security Token Service (STS) token that you obtained. For more information, see Overview.
endpoint The ID of the region. The region ID must be consistent with the region that is specified by the region parameter. Example: cn-hangzhou.
productName The name of the product. Set the value to ARMS.

  • A maximum of 100 API requests can be initiated per second for a single IP address.
  • ARMS provides public endpoints. If your ECS instance does not have a public bandwidth or a public IP address, you cannot make API requests by using tools such as Alibaba Cloud CLI or SDK. For information about how to initiate requests from an ECS instance in a VPC that is not accessible to the Internet, see Call the ARMS API over the internal network.
