Logappender Example

RocketMQ logappender provides log4j appender, log4j2 appender and logback appender for bussiness to use, below are config examples.

日志插件管理示例

RocketMQ日志插件管理提供了log4j插件、log4j2插件和logback插件，都可以在业务中使用，以下是如何设置的示例，

log4j

When using log4j properties config file,config as below.

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

log4j

log4j配置文件如下.

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

When using log4j xml config file,config it as this and also add a async appender:

<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>

使用xml文件配置log4j时，如下配置并添加一个异步插件：

<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>

log4j2

When using log4j2,config as this.If you want noneblock,just config an asyncAppender for ref.

<RocketMQ name="rocketmqAppender" producerGroup="yourLogGroup" nameServerAddress="yourRocketmqNameserverAddress"
     topic="yourLogTopic" tag="yourTag">
    <PatternLayout pattern="%d [%p] hahahah %c %m%n"/>
</RocketMQ>

log4j2

log4j2配置如下。如果你希望隐藏，就配置一个异步插件作为引用。【译者注：有问题】

<RocketMQ name="rocketmqAppender" producerGroup="yourLogGroup" nameServerAddress="yourRocketmqNameserverAddress"
     topic="yourLogTopic" tag="yourTag">
    <PatternLayout pattern="%d [%p] hahahah %c %m%n"/>
</RocketMQ>

logback

When using logback,an asyncAppender also needed.

<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>

logback

使用logback，异步插件也是必需的。

<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>
