Json Semi-structured log formats.
Text Default value. Unstructured log formats.

An unstructured format (text) is easy for humans to read but it is difficult for machine parsers to analyze and extract.

The simplicity and flexibility of JSON make it an ideal candidate for generating structured log statements; log data can be extracted and analyzed programmatically while messages remain easy for humans to understand.

JSON is the recommended log output format for most cases.
