When Cloud Log Service collects logs, information such as the collection rule name, collection time, collection file name, and the host IP is added to the log as key-value pairs. These fields are built-in fields of Cloud Log Service.

Example Log

The following is a log ingested in a cloud container engine scenario. The " message " field value is the original text of the log, and other fields are common built-in reserved fields.
