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-run-class.sh脚本，第一行增加jmx_port=9999即可。
jmx_port=9999
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 8273 1 99 02:32 pts/0 00:00:09 /opt/jdk1.8.0_201/bin/java -xmx1g -xms1g -server -xx:+useg1gc -xx:maxgcpausemillis=20 ...... kafka.kafka ./config/server.properties netstat -anop | grep 9999 tcp6 0 0 :::9999 :::* listen 8273/java off (0.00/0/0)
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: 1.7.5 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）。
下载jmxtrans rpm安装包
wget http://central.maven.org/maven2/org/jmxtrans/jmxtrans/270/jmxtrans-270.rpm --2019-04-10 03:18:14-- http://central.maven.org/maven2/org/jmxtrans/jmxtrans/270/jmxtrans-270.rpm resolving central.maven.org (central.maven.org)... 151.101.40.209 connecting to central.maven.org (central.maven.org)|151.101.40.209|:80... connected. http request sent, awaiting response... 200 ok length: 18750744 (18m) [application/x-rpm] saving to: ‘jmxtrans-270.rpm’ 100%[================================================================================================================================================================================>] 18,750,744 342kb/s in 43s

jmxtrans相关路径
jmxtrans安装目录：/usr/share/jmxtrans json文件默认目录：/var/lib/jmxtrans/ 日志路径：/var/log/jmxtrans/jmxtrans.log
配置json，jmxtrans的github上有一段示例配置

} ]
} ]
} ]
}
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
启动jmxtrans
service jmxtrans start starting jmxtrans...
