1. 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

1. 在prometheus配置文件中添加配置

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

1. 重启prometheus

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

1. 下载并导入dashboards
