i have written a plugin for this issue, but there is a problem that the `set $upstream_name -;` directive must be placed in the location block, so maybe we are missing an http_server_location_configuration_snippet item. 1. nginx config ``` log_format main escape=default '$remote_addr - [$remote_addr] - $remote_user [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" $request_length $request_time [$upstream_name] $upstream_addr $upstream_response_length $upstream_response_time $upstream_status $req_id $host [$scheme]'; location / { set $upstream_name -; } ``` 2. code ``` function _M.before_proxy(conf, ctx) -- maybe the ctx.matched_upstream can not access in the access phase ngx.var.upstream_name = ctx.matched_upstream.name core.log.warn("set $upstream_name=", ngx.var.upstream_name) end ``` 3. access log ``` 192.168.235.25 - [192.168.235.25] - - [07/Dec/2021:10:20:10 +0000] "GET /hostname HTTP/2.0" 200 33 "-" "curl/7.64.0" 48 0.003 [devops_flask-demo-online_8000] 172.16.214.127:8000 33 0.003 200 20d275ca0a73c2f141be75e22254b119 flask-demo.apisix.net [https] ``` -- This is an automated message from the Apache Git Service.
