Querying the Calling Data of a Service Version

Function

This API is used to query all versions of a service and their corresponding monitoring metric data. Data is retained for 30 days only.

Constraints

  • Region restrictions: Only the CN-Hong Kong region is supported.
  • API rate limiting: The total number of requests for this API from all users cannot exceed 1,000 within one minute.
  • User request limit: The number of requests for this API from a single user cannot exceed 200 within one minute.
  • Rate-limiting response: When the rate limit is exceeded, the API returns the HTTP status code 429 "Too Many Requests".
  • Retry suggestion: If the rate limit is exceeded, wait 60 seconds and try again.

Definition: Project ID. For details about how to obtain the project ID, see Obtaining a Project ID and Name.

Constraints: N/A

Range: The value can contain 32 characters. Only lowercase letters and digits are allowed.

Default Value: N/A

service_id

Yes

String

Definition: Service IDs to be queried. Services are filtered based on the input service ID list. If this parameter is not specified, all service names corresponding to the IDs are returned. You can obtain the service ID from the response body during service creation, or call the API for obtaining the service list. The service_id field indicates the service ID.

Range: N/A

Default Value: N/A

Table 3 Request body parameters

Parameter

Mandatory

Type

Description

api_keys

No

Array of strings

Definition: API key tag list, which is used for filtering.

MaaS services support API key calls.

Go to the API key management page to get the API key tag. The Tag field in the API key list shows the API key tag.

Constraints: N/A

Range:

  • Example for obtaining the online experience call data: api_keys: [""].
  • When obtaining the call data of some API keys, transfer the tags of the corresponding API keys. Example: api_keys: ["test01","test02"].
  • Example for obtaining the call data of online experience and some API keys: api_keys: ["test01", "test02", ""].
  • When obtaining all call data, do not use this parameter.

Default Value: N/A

ips

No

Array of strings

Definition: IP address list, which indicates the source IP addresses of the clients that have been called. If this parameter is not specified, all IP addresses are queried. To query the IP address, you can call the API for obtaining the IP address list.

Constraints: The value must be in the IP address format.

Default Value: N/A

start_time

Yes

Long

Definition: Timestamp of the start time, in milliseconds.

Constraints: The end time must be within 30 days from the start time.
