Kafka使用jmxtrans+influxdb+grafana监控JMX指标
来源：cnblogs　　作者：湮灭时空　　时间：2019/4/11 8:59:02　　对本文有异议

　　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

　　启动InfluxDB

service influxdb start
Redirecting to /bin/systemctl start influxdb.service

　　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

　　安装rpm包

rpm -ivh jmxtrans-270.rpm
Preparing... ################################# [100%]
Updating / installing...
1:jmxtrans-270-1 ################################# [100%]

 

　　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

{
  "servers" : [ {
    "port" : "1099",
    "host" : "w2",
    "queries" : [ {
      "obj" : "java.lang:type=Memory",
      "attr" : [ "HeapMemoryUsage", "NonHeapMemoryUsage" ],
      "resultAlias":"jvmMemory",
      "outputWriters" : [ {
        "@class" : "com.googlecode.jmxtrans.model.output.InfluxDbWriterFactory",
        "url" : "http://127.0.0.1:8086/",
        "username" : "admin",
        "password" : "admin",
        "database" : "jmxDB",
        "tags"     : {"application" : "kafka"}
      } ]
    } ]
  } ]
}

　　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...

　　查看日志没有报错即为成功

### NOT starting on installation, please execute the following statements to configure grafana to start automatically using systemd
 sudo /bin/systemctl daemon-reload
 sudo /bin/systemctl enable grafana-server.service
### You can start grafana-server by executing
 sudo /bin/systemctl start grafana-server.service
POSTTRANS: Running script

　　启动Grafana

service grafana-server start
Starting grafana-server (via systemctl):                   [  OK  ]

　　打开浏览器

http://127.0.0.1:3000

　　先输入默认用户名密码admin/admin

　　设置新密码

　　点击Add data source

 

　　选择InfluxDB

 

　　输入连接信息后点击Save & Test

　　通过后点击Back返回

　　左侧 + 可以创建或引入仪表盘

　　类似于数据库SQL语句，查询相应的指标

　　计算平均每秒数值可以使用如上语法，用当前值减1分钟之前的值再除以60

 

　　具体展示效果就看各位的审美能力，这里就不贴出来了。至此，Kafka的JMX指标监控就完成了。
