Note:
“Sum” is the sum of values obtained in a statistical period. Take ECS Internet traffic measurement as an example. The unit is KB/min and the statistical period is 5 minutes. Then the returned result is the total traffic in 5 minutes. Interfaces of the new version support query of ECS basic metric data, whereas interfaces of the old version do not. OpenAPI supports the query of metric data from the last 31 days. Dimension for each parameter is a JSON string, for example, {"instanceId":"i-23gyb3kkd"}.
