Setting Override

SkyWalking Satellite supports setting overrides by system environment variables. You could override the settings in satellite_config.yaml

System environment variables

• Example

  Override log_pattern in this setting segment through environment variables

logger:
  log_pattern: ${SATELLITE_LOGGER_LOG_PATTERN:%time [%level][%field] - %msg}
  time_pattern: ${SATELLITE_LOGGER_TIME_PATTERN:2006-01-02 15:04:05.000}
  level: ${SATELLITE_LOGGER_LEVEL:info}

If the SATELLITE_LOGGER_LOG_PATTERN environment variable exists in your operating system and its value is %msg, then the value of log_pattern here will be overwritten to %msg, otherwise, it will be set to %time [%level][%field] - %msg.
