Integrated Web Server

The integrated web server allows you to retrieve specific system or game information from a client or server via a web browser. For example: Minecraft's RCON and Query features do not allow you to obtain system CPU usage. This is just one of the many stats MDXLib allows you to retrieve. Below are more of the available stats the web server's API provides.


Mod Developers

MDX Also allows you to add additional web hooks. You can use these web hooks to trigger actions with feedback or retrieve information from the game.

You can add additional web hooks simply by calling "WebModule.REQUESTS().add()". There are two primary types of hooks at this moment. Standard and Command. Standard hooks allow you to specify your own handling technique, while Command hooks allow you to execute host system commands. This can be especially useful when designing a server infrastructure.

Additional information

Web Server Port: 7761

API Format: JSON

Web Hooks

NOTE: At the moment the system statistics API is only supported on machines running Microsoft Windows. Unix systems are not supported. The server MUST be running on Windows for this API to function. The game API works regardless.

System Statistics API Webhooks

/sys/stat/cpu/totalusage - Shows total CPU usage

/sys/stat/cpu/coreusage - Shows CPU usage on individual cores

/sys/stat/cpu/corefrequency - Shows the base clock speed of each core

/sys/stat/memory/total - Shows total system memory

/sys/stat/memory/available - Shows available system memory

/sys/stat/disk/usage - Shows all disk usage (performance, not capacity)

/sys/stat/disk/readbps - Shows read speed in bytes per second for all disks

/sys/stat/disk/writebps - Shows write speed in bytes per second for all disks

/sys/stat/power/milliwatts - Shows system power usage if your host has a current sensor. (Dell Servers are supported, Does not work in a VM)

/sys/stat/gpu/usage - Shows the usage of all GPU engines for each GPU installed.

Game API Webhooks

/game/world/players/ - Shows detailed information for all players connected to the server. Player IP, Username, Nickname, UUID, Dimension, and Health.


An example using one of these webhooks:

where is the remote IP address or domain name of your server, 7761 being the port to access the web server through, and the rest of the request being the web hook provided above.

The returned output for a system with an Intel Core i9 7920X processor looks like this (XE1 is the hostname):
