Real-time analytics
IMPORTANT: Unlike other Fastly APIs, the base URL for Real-time analytics is https://rt.fastly.com.
The real-time analytics API offers a standardized set of data about traffic received by a specified service in one-second time periods up to the last complete second.
Rate limiting
The real-time analytics API is rate limited internally. However, it is also cached behind Fastly with an expiration time of 1s. Under normal use there should be no reason for customers to hit that rate limit.
Data model
AggregateDelay | integer | How long the system will wait before aggregating messages for each second. The most recent data returned will have happened at the moment of the request, minus the aggregation delay. | |
Data | array | A list of records, each representing one second of time. | |
Timestamp | integer | Value to use for subsequent requests. |
Record data model
A list of records, each representing one second of time. The Data property provides access to measurement data for that time period, grouped in various ways.
aggregated | object | Aggregates measurements across all Fastly POPs. | |
datacenter | object | Groups measurements by POP. See the POPs API for details of POP identifiers. | |
recorded | integer | The Unix timestamp at which this record's data was generated. |
