我正在尝试运行 apm-server 使用 apm-agent 从基于 java 的应用程序收集数据并将其发送到 elasticsearch。 这是我的撰写文件:

但是在java应用程序日志中出现以下错误:

所有服务都绑定到单个“应用程序网络”。 那么java-agent和apm-server之间的连接问题可能是什么原因造成的呢? 如何调试从 java 到 elk 的流程?
APM Server 绑定到 localhost,暴露端口时阻止访问。要解决此问题,请将 apm.server.yml 更改为:
apm-server:
host: "localhost:8200"
至:
apm-server:
host: "0.0.0.0:8200"
