autoTraced: Whether to generate a trace id which can trace a life cycle, such as a http request. (default: true)
colorized: Whether the logs displayed on the console are in color. If it is true, it will have an impact on the logs in the log file. (default: false)
pivot: A separator used to help divide the business content and service content of one record. (default: '|')
template: The template of log content, using handlebars-helpers. (default: "{{label}} {{timestamp}} {{level}} {{traceId}} {{ip}} {{pid}} {{method}} {{httpPath}} {{timeCost}} {{pivot}} {{message}}")
