【问题标题】：Wildfly loadbalancer logWildfly 负载均衡器日志

【问题描述】：

我有一个设置，前面有一个负载均衡器（负载均衡器配置文件中的 wildly-11），后面有两个服务器节点（wildly-11）。现在我需要负载均衡器日志，它可以提供有关传输到的请求的详细信息哪个节点。谁能解释我们如何让这些日志出现？

【解决方案1】：

您可以在 WildFly 配置中为 io.undertow.server.handlers.proxy 包指定 DEBUG 日志级别。 standalone/configuration/standalone-load-balancer.xml 中的示例：

<logger category="io.undertow.server.handlers.proxy">
   <level name="DEBUG"/>
</logger>

之后，您将在日志中看到有关请求代理的信息。示例：
