DescribeDomainRealTimeSrcTrafficData - CDN - Alibaba Cloud Documentation Center

Queries the monitoring data of back-to-origin traffic for one or more specified accelerated domains. The data is collected every minute.

Operation description

You can call this operation up to 10 times per second per account.
If you do not specify the StartTime or EndTime parameter, the request returns the data collected in the last hour by default. If you specify both the StartTime and EndTime parameters, the request returns the data collected within the specified time range.

Time granularity

The time granularity varies with the time range specified by the StartTime and EndTime parameters. The following table describes the time period within which historical data is available and the data delay.

Time granularity	Maximum time range per query	Historical data available	Data delay
1 minute	1 hour	7 days	5 minutes
5 minutes	3 days	93 days	15 minutes
1 hour	31 days	186 days	4 hours
