6 Kafka监控

eagle可以监控多套kafka集群，kafka通过jmx拉取数据。开启jmx拉取端口9999

6.1 安装配置eagle

步骤1：修改kafka的启动命令

sudo vim $KAFKA_HOME/bin/kafka-server-start.sh

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

注意：在启动kafka之前要分发到其他节点吗，不然只会获取102的数据。

步骤2：上传eagle到software，解压到module

tar -zxvf kafka-eagle-bin-1.4.5.tar.gz
tar -zxvf kafka-eagle-web-1.4.5-bin.tar.gz -C /opt/module/

步骤3：修改eagle名称

[atguigu@hadoop102 module]$ mv kafka-eagle-web-1.4.5/ eagle

步骤4：给eagle的启动文件增加执行命令

[atguigu@hadoop102 eagle]$ cd bin/
[atguigu@hadoop102 bin]$ chmod 777 ke.sh

步骤5：修改配置文件conf/system-config.properties

# ① multi zookeeper & kafka cluster list
######################################
kafka.eagle.zk.cluster.alias=cluster1
cluster1.zk.list=hadoop102:2181,hadoop103:2181,hadoop104:2181

kafka.eagle.password=root

步骤6：添加环境变量（一定要添加）

export KE_HOME=/opt/module/eagle
export PATH=$PATH:$KE_HOME/bin

让环境变量生效source /opt/profile.d/my_env.sh

步骤7：启动eagle

 [atguigu@hadoop102 eagle]$ bin/ke.sh start
