KAFKA基础（十四）： Kafka监控

1 Kafka Eagle

1）修改kafka启动命令

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-1.4.5.tar.gz到集群/opt/software目录

3）解压到本地

[atguigu@hadoop102 software]$ tar -zxvf kafka-eagle-bin-1.4.5.tar.gz

4）进入刚才解压的目录

[atguigu@hadoop102 kafka-eagle-bin-1.4.5]$ ll
总用量 82932
-rw-rw-r--. 1 atguigu atguigu 84920710 8月  13 23:00 kafka-eagle-web-1.4.5-bin.tar.gz

5）将kafka-eagle-web-1.3.7-bin.tar.gz解压至/opt/module

[atguigu@hadoop102 kafka-eagle-bin-1.4.5]$ tar -zxvf kafka-eagle-web-1.4.5-bin.tar.gz -C /opt/module/

6）修改名称

[atguigu@hadoop102 module]$ mv kafka-eagle-web-1.4.5/ 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 conf/system-config.properties

######################################
# multi zookeeper&kafka cluster list
######################################
kafka.eagle.zk.cluster.alias=cluster1
cluster1.zk.list=hadoop102:2181,hadoop103:2181,hadoop104:2181

######################################

kafka.eagle.url=jdbc:mysql://hadoop102:3306/ke?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
kafka.eagle.username=root
kafka.eagle.password=123456

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
... ...
