dashode2

Realtime dashboard for nginx and other clf based webservers.

It was designed to debug and monitor nginx instances but it should work with anything that features a clf log.

Usage

Install

• npm install -g dashode2
• dashode

Env variables

• SCENARIO - Scenario type. ("local", "server" or "collector")
• HTTP_PORT - Dashboard server PORT. (8081)
• COLLECTOR_PORT - Collector server PORT. (8080)
• SERVER - Collector server. ("http://127.0.0.1:8080")
• LOG_PATH - Log path. ("/var/log/nginx/access.log")

Scenarios

local

• Spawns a collector server listening on port COLLECTOR_PORT (defaults to 8080)
• Spawns a dashboard server listening on port HTTP_PORT (defaults to 8081)
• Spawns a collector watching LOG_PATH (defaults to "/var/log/nginx/access.log") and reporting to collector server at SERVER (defaults to "http://127.0.0.1:8080")

server

• Spawns a collector server listening on port COLLECTOR_PORT (defaults to 8080)
• Spawns a dashboard server listening on port HTTP_PORT (defaults to 8081)

collector

• Spawns a collector watching LOG_PATH (defaults to "/var/log/nginx/access.log") and reporting to collector server at SERVER (defaults to "http://127.0.0.1:8080")

Support

• For all functionality use this log format:
• log_format main '$remote_addr - $remote_user - [$time_local] "$request" ' '$status $body_bytes_sent "$host" ' '"$http_user_agent" "$http_x_forwarded_for" "$http_referer" ' '$upstream_cache_status $request_time $upstream_response_time';

Authentication

• Dashode does not feature authentication, you should push that to a reverse proxy if you need it.
• Collector leverage env variables USERNAME and PASSWORD.

nginx authentication example

server {
 listen 1337;
 server_name ~^(.+)$;

 location / {
   auth_basic "Restricted";
   auth_basic_user_file /var/nginx/passwd;

   proxy_set_header Upgrade $http_upgrade;
   proxy_set_header Connection "upgrade";
   proxy_http_version 1.1;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header Host $host;

   proxy_pass http://127.0.0.1:8081/;
 }
}
