help request: how to configure file-log plugin?

[ederparaiso]

I tried to enable file-log plugin on my route but no file was created. What i missed? Any aditional config in other place/entity?

If I use a relative path, as doc example (logs/file.log), what is the base directory?

uri: /test/*
name: test
priority: 7
methods:
  - GET
  - OPTIONS
plugins:
  file-logger:
    path: /file.log
upstream:
  nodes:
    - host: my.host.com
      port: 443
      weight: 1
  timeout:
    connect: 6
    send: 6
    read: 6
  type: roundrobin
  scheme: https
  pass_host: pass
  keepalive_pool:
    idle_timeout: 60
    requests: 1000
    size: 320
status: 1

Also, is there any way to log apisix requests to upstream services? Does file-log plugin records it?

APISIX version: 3.0.0

I realized that it is due to permissions. I'm using this docker-compose as example:

https://github.com/apache/apisix-docker/blob/master/example/docker-compose.yml

Something wrong?

It's obvious the apisix workers cannot write the / dir.

If I remember correctly, the base dir for file-logger is /usr/local/apisix/conf?

It's seems obvious, but the same error occurs when I used the same path of docs example (a relative path "logs/file.log") ¯_(ツ)_/¯

Hi!

I'm also having trouble activating this plugin. Here is my route configuration:

{
  "uri": "/novocep/*",
  "name": "teste-cep",
  "methods": [
    "GET"
  ],
  "plugins": {
    "file-logger": {
      "disable": false,
      "path": "logs/file.log"
    },
    "key-auth": {
      "disable": false,
      "header": "Authorization",
      "hide_credentials": true
    }
  },
  "service_id": "432940486001427136",
  "labels": {
    "API_VERSION": "v1"
  },
  "status": 1
}

Here is the error I get in the error.log file:

2022/11/10 23:13:18 [error] 58#58: *19410847 [lua] file-logger.lua:117: write_file_data(): failed to open file: logs/file.log, error info: logs/file.log: Permission denied while logging request, client: 172.19.0.1, server: _, request: "GET /novocep/ws/64285000/json/?apikey=minha+chave+doidona HTTP/1.1", upstream: "https://165.227.126.241:443/novocep/ws/64285000/json/", host: "127.0.0.1:9080"

Does anyone have an idea what it could be? :(
