- “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"}.
