使用配置

  1. 下载jmx_exporter
https://github.com/prometheus/jmx_exporter
  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<>(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<>((?!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: [':']
  1. 重启prometheus
nohup ./prometheus  > prometheus.log 2>&1 &
  1. 下载并导入dashboards
https://grafana.com/grafana/dashboards/7727
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
