Querying API Calls Within a Period

Function

This API is used to query the number of times APIs in an API group are called within a period. The query is based on 1 minute. If the time range is within one hour, the server returns the number of API calls made every minute.

For security purposes, clear your operation records, including but not limited to records in the ~/.bash_history and /var/log/messages directories (if any), after running the curl command on the server to query information.

Debugging

You can use API Explorer to debug this API.
