Kafka之kafka-eagle监控

kafka-eagle是一个界面优美的监控网址，那么该如何配置？

1.修改/opt/module/kafka/bin/kafka-server-start.sh命令，并分发到集群的其他服务器上

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

2.安装

官方网址：EFAK

将安装包解压到/opt/module目录下

修改配置文件 /opt/module/eagle/conf/system-config.properties 修改以下命令

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

######################################
# offset保存在kafka
cluster1.kafka.eagle.offset.storage=kafka

######################################
# kafka metrics, 15 days by default
# 是否启动监控图表
kafka.eagle.metrics.charts=true
kafka.eagle.metrics.retain=15

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

3.加入环境变量

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

4.运行（主要记住账号密码）

 [example@hadoop102 eagle]$ ke.sh start
