如何配置JMX出口商以监视Prometheus中的Spring Boot应用程序

Question

使用JMX Exporter和Prometheus监视Spring Boot应用程序（TestMonoriting）。Prometheus和Spring Boot应用程序POD在Kubernetes群集中启动并运行。现在，痛苦是要使JMX出口商运行，并且应用程序应通过JMX暴露指标。

在testmonitoring应用程序中，应用程序文件具有以下设置：

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

现在如何将JMX出口商安装为代理：我已经下载了罐子并执行：

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

在config.yml->下面的Hostport：xx.x.x.x：30001（可作为服务可用的MySpring引导应用程序的目标端口）

抛出以下例外：

这种例外的原因是什么，只是无法弄清楚它？任何建议都将非常有用

尝试https://github.com/fabric8io/agent-bond
它可以正常工作。这样使用：

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