No reminder of port conflict when using the parameter "--use_external_processor" about viztracer

[gaogaotiantian]

external_processor only takes requests from localhost:10000, I doubt if it works well with remote port fowarding -> perfetto will make a request to localhost:9001 which should be your local external processor but it won't have access to it because it's remote. Remote part is not tested thoroughly for vizviewer and Perfetto probably does not take care of this case. If you are using remote, I would suggest do it with http processor because it's self-contained.
