Log Fields (RTLD WAF)

Log data is reported as a JSON document. Log format determines whether log data identification information will be included and how the data is formatted. Each type of log format is described below.

If log data uses either the JSON Array or JSON Lines log format, then it will not contain information that uniquely identifies a set of log data. If log data is delivered to a destination other than AWS S3, Azure Blob Storage, or Google Cloud Storage, then there is no way to check for gaps in sequence numbers when attempting to identify missing log data.

A log entry describes a HTTP/HTTPS request that was submitted to our CDN.

Top-Level Name/Value Pairs

Top-level name/value pairs are unavailable for the JSON Array and JSON Lines log formats. If you require this information, please choose the standard JSON log format.

Top-level name/value pairs are described below.
