第5章 Kafka监控
5.1 Kafka Eagle
1.修改kafka启动命令
修改kafka-server-start.sh命令中
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
fi
为
if [ "x$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
2.上传压缩包kafka-eagle-bin-1.3.7.tar.gz到集群/opt/software目录
3.解压到本地
[atguigu@hadoop102 software]$ tar -zxvf kafka-eagle-bin-1.3.7.tar.gz
4.进入刚才解压的目录
[atguigu@hadoop102 kafka-eagle-bin-1.3.7]$ ll
总用量 82932
-rw-rw-r--. 1 atguigu atguigu 84920710 8月 13 23:00 kafka-eagle-web-1.3.7-bin.tar.gz
5.将kafka-eagle-web-1.3.7-bin.tar.gz解压至/opt/module
[atguigu@hadoop102 kafka-eagle-bin-1.3.7]$ tar -zxvf kafka-eagle-web-1.3.7-bin.tar.gz -C /opt/module/
6.修改名称
[atguigu@hadoop102 module]$ mv kafka-eagle-web-1.3.7/ eagle
7.给启动文件执行权限
[atguigu@hadoop102 eagle]$ cd bin/
[atguigu@hadoop102 bin]$ ll
总用量 12
-rw-r--r--. 1 atguigu atguigu 1848 8月 22 2017 ke.bat
-rw-r--r--. 1 atguigu atguigu 7190 7月 30 20:12 ke.sh
[atguigu@hadoop102 bin]$ chmod 777 ke.sh
8.修改配置文件

kafka.eagle.zk.cluster.alias=cluster1
cluster1.zk.list=hadoop102:2181,hadoop103:2181,hadoop104:2181

kafka.eagle.password=000000
9.添加环境变量
export KE_HOME=/opt/module/eagle
export PATH=$PATH:$KE_HOME/bin
注意：source /etc/profile
10.启动
[atguigu@hadoop102 eagle]$ bin/ke.sh start
