Start Arguments

System Parameters

  • -config.from: The default is file, that is, the default configuration method using the file. Optional: env, in which case the configuration will be read from environment variables (reload is not supported at this time).
  • -config.system: The default is loggie.yml, which indicates the path and file name of the specified Loghie system configuration. (if -config.from=env, configuration will be read from environment variables）
  • -config.pipeline: The default is pipelines.yml, which indicates the path where the Pipeline configuration file is located. You need to fill in the path that matches the glob, such as the specific path and file name /etc/loggie/pipelines.yml, or glob matching, such as /etc/loggie/*.yml. (if -config.from=env, configuration will be read from environment variables)

Warning

Note that if config.pipeline=/etc/loggie, loggie file in /etc will be matched instead of files in /etc/loggie. Please avoid similar settings.

  • -meta.nodeName: By default, the hostname of the system will be used. In Kubernetes, the Downward API will be used to inject nodeName. In general, no separate configuration is required

Log Parameters:

  • -log.level: log level, default info, can be configured as debug, info, warn and error.
  • -log.jsonFormat: whether to output the log in json format, default false.
  • -log.enableStdout: whether to output standard output log, default true.
  • -log.enableFile: whether to output log files, default false.
  • -log.directory: path of the log file, default /var/log. It takes effect when log.enableFile=true.
  • -log.filename: name of the log file, default loggie.log, generally used with log.directory.
  • -log.maxSize: maximum file size when the log is rotated, default 1024MB.
  • -log.maxBackups: maximum number of files to keep in log rotation, default 3.

Info

Loggie’s log rotation uses lumberjack library.
