How to customize Rails log messages to JSON format [closed]
You can configure rails to specify your own log formatter:
config.log_formatter defines the formatter of the Rails logger. This option defaults to an instance of ActiveSupport::Logger::SimpleFormatter for all modes except production, where it defaults to Logger::Formatter.
You can provide your own class to output the log information:
class MySimpleFormatter < ActiveSupport::Logger::SimpleFormatter def call(severity, timestamp, _progname, message) { type: severity, time: timestamp, message: message }.to_json endendTo configure your new class you'd need to add a config line:
config.log_formatter = MySimpleFormatter.new
