第5章、Kafka监控

一、Kafka Eagle

• 修改 kafka 启动命令.修改 kafka-server-start.sh 命令中

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
fi

　　改为

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
export KAFKA_HEAP_OPTS="-server -Xms2G -Xmx2G -XX:PermSize=128m -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:ParallelGCThreads=8 -XX:ConcGCThreads=5 -XX:InitiatingHeapOccupancyPercent=70"
export JMX_PORT="9999"
#export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
fi

　　注意：修改之后在启动 Kafka 之前要分发之其他节点

• 上传压缩包 kafka-eagle-bin-1.3.7.tar.gz 
• 解压到本地
• 进入刚才解压的目录，修改名称
• 给启动文件执行权限

chmod 777 ke.sh

• 修改配置文件
