Troubleshooting

This section covers common problems that may arise when you use Spring Cloud Gateway.

Log Levels

The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels:

  • org.springframework.cloud.gateway

  • org.springframework.http.server.reactive

  • org.springframework.web.reactive

  • org.springframework.boot.autoconfigure.web

  • reactor.netty

  • redisratelimiter

Wiretap

The Reactor Netty HttpClient and HttpServer can have wiretap enabled. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively.
