Kafka使用jmxtrans+influxdb+grafana监控JMX指标
最近在搞Kafka集群监控，之前也是看了网上的很多资料。之所以使用jmxtrans+influxdb+grafana是因为界面酷炫，可以定制化，缺点是不能操作Kafka集群，可能需要配合Kafka Manager一起使用。
环境信息
- CentOS Linux release 7.6.1810 (Core)
- jdk1.8.0_201
- zookeeper-3.4.14
- kafka_2.11-2.2.0
开启Kafka JMX端口
JMX（Java Management Extensions，即Java管理扩展）是一个为应用程序、设备、系统等植入管理功能的框架。JMX可以跨越一系列异构操作系统平台、系统体系结构和网络传输协议，灵活的开发无缝集成的系统、网络和服务管理应用。Kafka做为一款Java应用，已经定义了丰富的性能指标，(可以参考Kafka监控指标)，通过JMX可以轻松对其进行监控。
在${KAFKA_HOME}/bin/路径下修改kafka-server-start.sh脚本，第一行增加JMX_PORT=9999即可。
JMX_PORT=
重启Kafka
./bin/kafka-server-stop.sh
./bin/kafka-server-start.sh -daemon ./config/server.properties
重启后查看Kafka以及JMX端口状态
ps -ef | grep kafka
root : pts/ :: /opt/jdk1..0_201/bin/java -Xmx1G -Xms1G -server -XX:+UseG1GC -XX:MaxGCPauseMillis= ...... kafka.Kafka ./config/server.properties netstat -anop | grep
tcp6 ::: :::* LISTEN /java off (0.00//)
安装InfluxDB
InfluxDB是一个时间序列数据库，用于处理海量写入与负载查询。InfluxDB旨在用作涉及大量时间戳数据的任何用例（包括DevOps监控，应用程序指标，物联网传感器数据和实时分析）的后端存储。
下载InfluxDB rpm安装包

使用InfluxDB客户端
influx
Connected to http://localhost:8086 version 1.7.5
InfluxDB shell version: 1.7.
Enter an InfluxQL query
>
创建用户和数据库
> CREATE USER "admin" WITH PASSWORD 'admin' WITH ALL PRIVILEGES
> create database "jmxDB"
创建完成InfluxDB的用户和数据库暂时就够用了，其它简单操作如下，后面会用到
#创建数据库
create database "db_name"
#显示所有的数据库
show databases
#删除数据库
drop database "db_name"
#使用数据库
use db_name
#显示该数据库中所有的表
show measurements
#创建表，直接在插入数据的时候指定表名
insert test,host=127.0.0.1,monitor_name=test count=1
#删除表
drop measurement "measurement_name"
#退出
quit
安装jmxtrans
jmxtrans的作用是自动去jvm中获取所有jmx格式数据，并按照某种格式（json文件配置格式）输出到其他应用程序（本例中的influxDB）。

- host：监控服务器
- port：jmx端口
- obj：对应jmx的ObjectName，就是我们要监控的指标
- attr：对应ObjectName的属性，可以理解为我们要监控的指标的值
- resultAlias：对应metric 的名称，在InfluxDB里面就是MEASUREMENTS名
- tags：对应InfluxDB的tag功能，对与存储在同一个MEASUREMENTS里面的不同监控指标可以做区分，我们在用Grafana绘图的时候会用到，建议对每个监控指标都打上tags
