搭建 Jmx_exporter + Prometheus + Grafana 监控kafka_kafka jmx export

一、 启动jmx_exporter

1. 下载并打包(mvn package)jmx_exporter

https://github.com/prometheus/jmx_exporter
1

测试jar包(kafka的jmx端口为9898):

java -cp collector/target/collector-0.15.1-SNAPSHOT.jar  io.prometheus.jmx.JmxScraper  service:jmx:rmi:///jndi/rmi://localhost:9898/jmxrmi
1

2. 修改example_configs\kafka-2_0_0.yml

在首行添加kafka的jmx地址:

hostPort: localhost:9898
1

3. 启动jmx_exporter为httpserver

Windows下启动：

java -cp .\jmx_prometheus_httpserver\target\jmx_prometheus_httpserver-0.15.1-SNAPSHOT-jar-with-dependencies.jar io.prometheus.jmx.WebServer 9997 .\example_configs\kafka-2_0_0.yml
1

4. 测试：

访问http://localhost:9997， 能正确返回数据

二、 启动Prometheus

1. 下载并解压缩Prometheus

https://prometheus.io/download/
1

2. 修改prometheus.yml

在scrape_configs节点下添加：

  - job_name: 'kafka_jmx_exporter'
    static_configs:
    - targets: ['localhost:9997']
