API Documentation

Documentation is auto generated by ASP.NET and can be accessed from /swagger/v1/swagger.json You can use insomnia to view the documentation or alternatively you can use the manually created doc file located in /docs/insomnia.json.

When you contribute make sure to store it in docs/insomnia.json.

Note: make sure you have insomnia-documenter installed (Get it here: https://github.com/jozsefsallai/insomnia-documenter)

To view the docs run:

    npx serve

NGINX Configuration

This configuration can be added to /etc/nginx/sites-available/default and will reverse proxy to port 36676. It should take the real IP back to the API as well in case we need to rate limit a specific IP.

server {
    server_name   example.com;
    location / {
        proxy_pass         https://localhost:36677;

        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
        proxy_set_header   X-Real-IP $remote_addr;
    }
}

NGINX Configuration with Plesk

This is a little more complicated because Plesk screws up NGINX default config files.

1. Add your domain or subdomain to Plesk
2. Go to Plesk->DOMAIN->Apache & Nginx settings and change the settings below:
   • Disable Nginx as a proxy (untick):
3. Apply and Save these settings
4. In the same window, add the following to Additional Nginx directives:

location / {
    proxy_pass         https://localhost:36677;

    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection keep-alive;
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;
}

5. Make sure to enable SSL. !!! WARNING: disable any CloudFlare proxy !!!

Service configuration

1. Add ServerMon-api.service to /etc/systemd/system/ (For example /etc/systemd/system/ServerMon-api.service)
2. Copy the binaries with all its dependencies to /opt/ServerMon-api/ or any other place (Make sure to update the .service file to match the new binaries path!)
3. Enable the service using sudo systemctl enable ServerMon-api
4. Start the service using sudo systemctl start ServerMon-api
5. Grab a ☕/🍵 and relax ~

Working remotely?

You can pass through your debugging session to a nginx reverse proxy server to access it normally by using SSH.

ssh -R 36677:localhost:36677 -R 36676:localhost:36676 user@example.com
