For example, if you set the Period parameter to 60, the StartTime parameter to 2021-05-08 08:00:00, and the EndTime parameter to 2021-05-08 10:00:00, the monitoring data of the last 60 seconds in the time range is queried.
     *     *   If you set the `Period` parameter to 3600, the specified time range must be less than or equal to 2 days. For example, if you set the StartTime parameter to 2021-05-08 08:00:00 and the EndTime parameter to 2021-05-10 08:00:00, the monitoring data of the last 3,600 seconds in the time range is queried.
