go-mumble-ping

Microservice that translates the Mumble Ping to JSON.

Why?

The murmur server offers a way to see how many users are active without connecting/logging in. Since Mumble is used mostly by communities, it would be great if they could show a user counter on their website. Unfortunately this functionality is only exposed through a custom formatted UDP datagram and therefore not usable by ordinary javascript.

go-mumble-ping aims to bridge that gap by exposing a webserver that returns JSON on its / route (see usage). The mumble server is queried when the webserver is queried. Successful responses are cached for 15 seconds.

Requirements

Have a local go install.

Usage

Build an run:

$ go run .

In another shell, query the server:

$ curl -s http://localhost:8080/
{
    "server_version": "1.3.4",
    "last_update": 1674767226,
    "connected_users": 5,
    "max_users": 100,
    "bandwidth": 72000
}

In case of an error, the server returns an HTTP 5xx status code and a JSON object with a message key containing the error message.

You can run go-mumble-ping on its own, but it's probably best to integrate it into an existing nginx as an upstream server and binding it to a path like /mumble_status.json.

Configuration

All configuration is done via environment variables.

Environment Variables

Variable	Description
MUMBLE_HOST	The hostname of your mumble server, defaults to localhost.
MUMBLE_PORT	The port of your mumble server, defaults to 64738.
PORT	The port go-mumble-ping will listen on, defaults to 8080.

Project Status

The basic functionality is stable. No further development to be expected.
