来自Kafka Producer的过多控制台消息

Question

如何控制Kafka Producer或Consumer的控制台日志记录级别？我在Scala中使用Kafka 0.9 API。

每次调用send上的KafkaProducer时，控制台都会输出如下所示的输出。这可能表明我没有正确设置KafkaProducer，而不仅仅是过度记录的问题？

17:52:21.236 [pool-10-thread-7] INFO  o.a.k.c.producer.ProducerConfig - ProducerConfig values: 
compression.type = none
metric.reporters = []
metadata.max.age.ms = 300000
.
.
.

在Kafka服务器和Zookeeper看的properties文件中有日志配置，但我认为这些不会影响Kafka客户端。更改这些文件中的某些日志记录配置，并重新启动Kafka服务器和Zookeeper以便重新加载这些文件，但仍未解决问题。

谢谢

Answer 1

将其添加到您的客户端代码中。

      Logger.getLogger("org").setLevel(Level.WARNING);
      Logger.getLogger("akka").setLevel(Level.WARNING);       
      Logger.getLogger("kafka").setLevel(Level.WARNING);

在logback.xml上添加名为org.apacha.kafka的记录器

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <layout class="ch.qos.logback.classic.PatternLayout">
        <Pattern>
            %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
        </Pattern>
    </layout>
</appender>

<logger name="org.apache.kafka" level="warn">
    <appender-ref ref="STDOUT" />
</logger>


<root level="info">
    <appender-ref ref="STDOUT" />
</root>

正确配置logback解决了我的问题：http://www.mkyong.com/logging/logback-xml-example/
