Discussion on: Migrating off of Log4j 2.x

[Phil Harron]

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>

Many thanks
Phil
