如何为 Kafka 生产者配置日志记录? [英] How to configure logging for Kafka producers?

问题描述

我正在使用 Kafka 生产者客户端，我的项目中没有任何 log4j 配置.

I am using Kafka producer client and i don't have any log4j configuration in my project.

在运行时，程序打印了很多我真的不想要的 Kafka 调试日志.

On running, the program prints a lot of Kafka Debug logs which i really don't want.

因此，我尝试添加 log4j.properties 以将日志级别设置为 ERROR，如下所示，这似乎不起作用:

So, i tried to add a log4j.properties to set log level to ERROR as below which does not seem to work:

log4j.rootLogger=ERROR

如何更改 Kafka 日志级别?

How do i change Kafka Log Level?

推荐答案

在运行客户端时使用命令行标志 -Dlog4j.configuration=file:/path/to/log4j.properties.

Use the command line flag -Dlog4j.configuration=file:/path/to/log4j.properties when running your client.

示例 log4j 属性文件:

Example log4j property files:

• https://github.com/apache/kafka/blob/trunk/config/tools-log4j.properties
  • 被镜子制造商等工具使用，实际上只是标准输出
  • 被 kafka 服务器等工具使用

  对于导致调用 kafka-run-class.sh 的镜像制造商和其他工具，您可以使用环境变量 KAFKA_LOG4J_OPTS(设置为类似 -Dlog4j.configuration=file:/path/to/log4j.properties) 更改日志配置.请参阅:https://github.com/apache/kafka/blob/0.10.2/bin/kafka-run-class.sh#L158

  For mirror maker and other tools that result in a call to kafka-run-class.sh, you can use the env variable KAFKA_LOG4J_OPTS (set to something like -Dlog4j.configuration=file:/path/to/log4j.properties) to change the logging configuration. See: https://github.com/apache/kafka/blob/0.10.2/bin/kafka-run-class.sh#L158

  我用于测试的镜像制造商的 log4j.properties 文件示例.

  Example of my log4j.properties file for mirror maker that I use for testing.

  # https://github.com/apache/kafka/blob/trunk/config/tools-log4j.properties
  
  log4j.rootLogger=DEBUG, stderr
  
  log4j.appender.stderr=org.apache.log4j.ConsoleAppender
  log4j.appender.stderr.layout=org.apache.log4j.PatternLayout
  log4j.appender.stderr.layout.ConversionPattern=[%d] %p %m (%c)%n
  log4j.appender.stderr.Target=System.err
