使用 JMX 导出器和 Prometheus 监控 Spring Boot 应用程序（TestMonitoring）。Prometheus 和 Spring Boot 应用程序 Pod 在 kubernetes 集群中启动并运行。现在的痛苦是让 JMX 导出器运行，并且应用程序应该通过 JMX 公开指标。

在 TestMonitoring application 中，application.properties 文件具有以下设置：

endpoints.jmx.enabled=true
spring.jmx.enabled=true

现在如何将 JMX 导出器安装为代理：我已经下载了 jar 并执行了：

java -javaagent:./jmx_prometheus_javaagent-0.9.jar=1234:config.yml

在 config.yml -> 以下 hostPort:xx.xxx:30001 （可作为服务使用的 myspring 引导应用程序的目标端口）

抛出以下异常：

这种异常的原因可能是什么，只是无法弄清楚？任何建议都会非常有帮助

试试https://github.com/fabric8io/agent-bond
它工作正常。像这样使用它：

-javaagent:/opt/agent-bond/agent-bond.jar=/etc/config/agent-bond.properties
