    Metrics

    The following table describes the metrics that available for all access types. When you perform a query operation, you only need to replace $callType with a specific access type. For more information about access types, see the Service access types and available dimensions section.

    For example, to query the number of HTTP requests, you only need to change arms_$callType_requests_count to arms_http_requests_count.
