　　在Kafka的监控系统中有很多优秀的开源监控系统。比如Kafka-manager，open-faclcon，zabbix等主流监控工具均可直接监控kafka。Kafka集群性能监控可以从消息网络传输，消息传输流量，请求次数等指标来衡量集群性能。这些指标数据可以通过访问kafka集群的JMX接口获取。

　　由于Kafka Eagle监控系统核心模块采用java编程语言实现，因此启动Kafka Eagle 监控系统需要依赖Java运行环境（JDK），建议使用java 7以上版本，推荐使用JDK1.8。关于jdk的安装我就不废话了，大家自行安装一下。

2>.解压安装包并创建软连接 

[root@node105 kafka-eagle]# ll

[root@node105 kafka-eagle]#

3>.为Kafka Eagle配置环境变量（“/etc/profile”） 

[root@node105 kafka-eagle]# tail /etc/profile
export GOROOT=/usr/lib/golang
export GOPATH=/home/yinzhengjie/golang

#ADD open-falcon path by yinzhengjie
export FALCON_HOME=/yinzhengjie/open-falcon/workspace
export WORKSPACE=/open-falcon

#ADD kafka-Eagle path by yinzhengjie
export KE_HOME=/soft/kafka-eagle
export PATH=$PATH:$KE_HOME/bin
[root@node105 kafka-eagle]# 
[root@node105 kafka-eagle]# chmod +x /soft/kafka-eagle/bin/ -R   　　#这个目录下有2个脚本，当你启动服务时，会多处一个ke.pid的文件，用于存放进程pid的，这一步必须得做，没有权限的话，你没法启动服务哟！
[root@node105 kafka-eagle]# 
[root@node105 kafka-eagle]# source  /etc/profile
[root@node105 kafka-eagle]#

4>.编辑配置文件（/soft/kafka-eagle/conf/system-config.properties）

[root@node105 kafka-eagle]# ke.sh start　　　　　　　　#启动Kafka Eagle系统

6>.启动成功的标志

7>.遇到的一系列坑

　　启动时报错如下：

[root@node105 kafka-eagle]# ke.sh start
Starting : KE Service Check ...
Error: The JAVA_HOME environment variable is not defined correctly.
Error: This environment variable is needed to run this program.
[root@node105 kafka-eagle]#

 

　　查看启动脚本（vi /soft/kafka-eagle/bin/ke.sh ） 

发现我的java环境已经配置好啦～可以直接查看相应的环境变量～

[root@node105 kafka-eagle]# java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
[root@node105 kafka-eagle]# 
[root@node105 kafka-eagle]# 
[root@node105 kafka-eagle]# echo $JAVA_HOME
/soft/jdk
[root@node105 kafka-eagle]#

　　解决方案如下：

8>.查看端口是否存在

[root@node105 kafka-eagle]# hostname
node105.yinzhengjie.org.cn
[root@node105 kafka-eagle]# 
[root@node105 kafka-eagle]# 
[root@node105 kafka-eagle]# netstat -untalp | grep 8048
tcp6       0      0 :::8048                 :::*                    LISTEN      5184/java           
[root@node105 kafka-eagle]#

9>.访问kafka eagle的webUI服务（用户名：admin，密码：123456）

http://node105.yinzhengjie.org.cn:8048/ke/

10>.登陆成功的界面如下

 

 

三.Kafka Eagle快速入门

　　都已经部署成功了，剩下给大家介绍界面的功能感觉是多余的，不过大家也别嫌我啰嗦，部署成功了，大家点点鼠标也就知道咋回事了～其实和Kafka manager差不多多少～只不过功能要比kafka manager更多一点而已啦！

1>.创建topic

2>.查看topic

 

3>.kafka SQL查询界面（我没咋用过哈～有时间可以研究研究～）

 

4>.发送消息到指定的topic

 

　　别忘了启动一个消费者进行测试，查看是否能拿到数据，很显然，我是拿到数据啦：

5>.查看所有消费者的情况

 

6>.查看正在监控的集群

 

7>.监控多个kafka集群

 

8>.zookeeper客户端操作命令

 

9>.性能指标监控（broker总的流量监控）

 

10>.通过JMX获取数据，监控Kafka客户端，生产端，消息数量，请求数量，处理时间和其他数据，以可视化性能。

11>.kafka系统管理

 

12>.关于kafka Eagle脚本的命令

　　详情请参考官网：https://ke.smartloli.org/3.Manuals/6.Shell.html。说句实话，我一般不咋夸人，这家公司官网的图解做的很好，在这里，我本人希望Kafka Eagle功能越来越强，比如支持微信，集群压力测试等等。
