Logs

JetProxy uses Logback as the underlying logging framework. Logback is a powerful and flexible logging system, widely used for its performance and configurability. By default, JetProxy writes logs to stdout in text format. The default configuration provides simplicity and works well for development environments without additional setup.

Default Settings​

  1. Root Logger Level: INFO
    • This means only INFO, WARN, and ERROR messages are logged by default.
  2. Appender: ConsoleAppender
    • Logs are written to the standard output (console).
    • The default log format is:
    %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
    Example: 
    2025-01-24 13:30:19 INFO io.jetproxy.MainProxy - JetProxy server started on port 8080

Configuring Logs

To dynamically set logging configuration via a YAML file, add:

logging:
  root:
    level: INFO
  appenders:
    - name: STDOUT
      className: "ch.qos.logback.core.ConsoleAppender"
      encoder:
        pattern: "%d{yyyy-MM-dd HH:mm:ss} %-1level %logger{36} - %msg%n"
