                 URL: http://jira.qos.ch/browse/LBCLASSIC-260
             Project: logback-classic
          Issue Type: New Feature
          Components: appender
    Affects Versions: 0.9.28
            Reporter: Tomasz Nurkiewicz
            Assignee: Logback dev list


Provide built-in utility appender that silently stores last few logging 
messages and dumps them (forwards to a target appender) only when an error 
occurs. Older logging events are replaced with new ones. This is a 
configuration example:

<configuration>
  <appender name="REC" class="ch.qos.logback.classic.RecordingAppender">
    <appender-ref ref="STDOUT"/>

    <maxEvents>1000</maxEvents>
    <dumpThreshold>WARN</dumpThreshold>
    <expiryTimeMs>15000</expiryTimeMs>
  </appender>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%-4relative [%thread] %-5level - %msg%n</pattern>
    </encoder>
  </appender>

  <root level="DEBUG">
    <appender-ref ref="REC"/>
  </root>
</configuration>

Such an appender is crafted manually by several users, it would be nice to 
provide it out of the box. I already implemented this feature (100% test 
coverage):
