使用配置

1. 下载jmx_exporter

https://github.com/prometheus/jmx_exporter

2. 创建jmx_exporter配置文件

vim simple-config.yml

lowercaseOutputLabelNames: true
lowercaseOutputName: true
whitelistObjectNames: ["java.lang:type=OperatingSystem"]
blacklistObjectNames: []
rules:
  - pattern: 'java.lang<type=OperatingSystem><>(committed_virtual_memory|free_physical_memory|free_swap_space|total_physical_memory|total_swap_space)_size:'
    name: os_$1_bytes
    type: GAUGE
    attrNameSnakeCase: true
  - pattern: 'java.lang<type=OperatingSystem><>((?!process_cpu_time)w+):'
    name: os_$1
    type: GAUGE
    attrNameSnakeCase: true

javaagent启动应用
java -javaagent:./jmx_prometheus_javaagent-0.14.0.jar=8080:simple-config.yaml -jar yourJar.jar

3. 在prometheus配置文件中添加配置

scrape_configs:
  - job_name: 'java'
    static_configs:
    - targets: ['<host>:<port>']

4. 重启prometheus

nohup ./prometheus  > prometheus.log 2>&1 &

5. 下载并导入dashboards

https://grafana.com/grafana/dashboards/8563
注：8563模板对7727有依赖，所以需全部安装，否则不能正常使用
