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

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
