使用jmx_agent监控java程序
1.下载jmx_prometheus_javaagent.jar
从https://github.com/prometheus/jmx_exporter/releases下载最新版本的jmx_prometheus_javaagent.jar
2.创建一个名为jmx_exporter_config.yml的文件
用于配置jmx_prometheus_javaagent.jar的监控参数。该文件应该包含要暴露的MBean的名称，以及它们要被暴露的端口号。

3.使用agent方式启动java应用程序的同时启动jmx
java -javaagent:/path/to/jmx_prometheus_javaagent.jar=8080:/path/to/jmx_exporter_config.yml -jar myapp.jar
4.配置Prometheus.yml,并重启prometheus
scrape_configs:
- job_name: 'myapp'
static_configs:
- targets: ['localhost:8080']
