Method: Betterlog::Log::Event#to_json

Defined in:
lib/betterlog/log/event.rb

#to_json(*a) ⇒ String

Converts the log event to a JSON string representation.

This method generates a JSON-encoded string of the log event’s data, providing a structured format suitable for logging and transmission. In cases where JSON generation fails due to encoding issues or other errors, it falls back to a minimal JSON representation containing only the severity and a cleaned-up message to ensure logging functionality remains intact.

Returns:

  • (String) —

    A JSON string representation of the log event
