kafka监控指标项

监控配置

​ kafka基本分为broker、producer、consumer三个子项，每一项的启动都须要用到 $KAFKA_HOME/bin/kafka-run-class.sh 脚本，在该脚本中，存在如下语句：

if ...
  KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false  -Dcom.sun.management.jmxremote.ssl=false"
fi
if ...
  KAFKA_JMX_OPTS="$KAFKA_JMX_OPTS -Dcom.sun.management.jmxremote.port=$JMX_PORT "
fi

​ 在启动kafka的过程当中，只要指定 JMX_PORT 的值，便可对broker、producer、consumer进行监控。目前有两种方法，

• 在 $KAFKA_HOME/bin/kafka-server-start.sh、 $KAFKA_HOME/bin/kafka-console-consumer.sh、 $KAFKA_HOME/bin/kafka-console-producer.sh 三个脚本中分别添加 $JMX_PORT=XXXX 语句，可是只适用于使用console方式对topic进行使用的状况。
• 修改$KAFKA_HOME/bin/kafka-run-class.sh 脚本中的上述语句，使其端口随机变化，能够经过 ps -ef |grep kafka 命令来获取随机的端口号，来进行监控
