Logappender样例

---

RocketMQ日志提供log4j、log4j2和logback日志框架作为业务应用，下面是配置样例

1 log4j样例

按下面样例使用log4j属性配置

log4j.appender.mq=org.apache.rocketmq.logappender.log4j.RocketmqLog4jAppender

log4j.appender.mq.Tag=yourTag

log4j.appender.mq.Topic=yourLogTopic

log4j.appender.mq.ProducerGroup=yourLogGroup

log4j.appender.mq.NameServerAddress=yourRocketmqNameserverAddress

log4j.appender.mq.layout=org.apache.log4j.PatternLayout

log4j.appender.mq.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-4r [%t] (%F:%L) %-5p - %m%n

按下面样例使用log4j xml配置来使用异步添加日志

<appender name="mqAppender1"class="org.apache.rocketmq.logappender.log4j.RocketmqLog4jAppender">

  <param name="Tag" value="yourTag" />

  <param name="Topic" value="yourLogTopic" />

  <param name="ProducerGroup" value="yourLogGroup" />

  <param name="NameServerAddress" value="yourRocketmqNameserverAddress"/>

  <layout class="org.apache.log4j.PatternLayout">

      <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss}-%p %t %c - %m%n" />

  </layout>

</appender>

<appender name="mqAsyncAppender1"class="org.apache.log4j.AsyncAppender">

  <param name="BufferSize" value="1024" />

  <param name="Blocking" value="false" />

  <appender-ref ref="mqAppender1"/>

</appender>

2 log4j2样例

用log4j2时，配置如下，如果想要非阻塞，只需要使用异步添加引用即可

<RocketMQ name="rocketmqAppender" producerGroup="yourLogGroup" nameServerAddress="yourRocketmqNameserverAddress"

   topic="yourLogTopic" tag="yourTag">

  <PatternLayout pattern="%d [%p] hahahah %c %m%n"/>

</RocketMQ>

3 logback样例

<appender name="mqAppender1"class="org.apache.rocketmq.logappender.logback.RocketmqLogbackAppender">

  <tag>yourTag</tag>

  <topic>yourLogTopic</topic>

  <producerGroup>yourLogGroup</producerGroup>

  <nameServerAddress>yourRocketmqNameserverAddress</nameServerAddress>

  <layout>

      <pattern>%date %p %t - %m%n</pattern>

  </layout>

</appender>

<appender name="mqAsyncAppender1"class="ch.qos.logback.classic.AsyncAppender">

  <queueSize>1024</queueSize>

  <discardingThreshold>80</discardingThreshold>

  <maxFlushTime>2000</maxFlushTime>

  <neverBlock>true</neverBlock>

  <appender-ref ref="mqAppender1"/>

</appender>
