Hello, thanks for the helpful information.

One thing that caught me out in the logback.xml with rolling file appender example was the appenders are not defined in the correct order, which ultimately caused no logs to be written to my log file.

It should be:

  <appender name="LogFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>/var/log/myapp/myapp.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <fileNamePattern>/var/log/myapp/myapp-%d{yyy-MM-dd}.log.gz</fileNamePattern>
      <maxHistory>7</maxHistory>
    </rollingPolicy>
    <encoder>
      <pattern>%d %p %c{1} [%t] %m%n</pattern>
    </encoder>
  </appender>
  <appender name="AsyncLogFile" class="ch.qos.logback.classic.AsyncAppender">
    <appender-ref ref="LogFile" />
  </appender>
Enter fullscreen mode Exit fullscreen mode

Many thanks
Phil
