Question

我有一个设置，其中有一个负载平衡器（负载平衡器配置文件中的wildly-11）在前面，两个服务器节点（wildly-11）在后面。现在我需要负载平衡器日志，该日志可以提供有关将请求传输到的详细信息谁能解释我们如何使这些日志出现？

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

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

此后，您将在日志中看到有关请求代理的信息。示例：

13:05:06,274 DEBUG [io.undertow.server.handlers.proxy] (default I/O-13) Sending request ClientRequest{path='/xxx-app', method=GET, protocol=HTTP/1.1} to target /127.0.0.1:8009 for exchange HttpServerExchange{ GET /xxx-app request {Accept=[text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8], Accept-Language=[en-US,en;q=0.5], Cache-Control=[max-age=0], Accept-Encoding=[gzip, deflate], User-Agent=[...], Connection=[keep-alive], Cookie=[JSESSIONID=B9mIIaGz2QYcPBbODJxvY04wjjRnfSz0r2iYh7VQ.node6], Upgrade-Insecure-Requests=[1], Host=[localhost:8080]} response {}}
