wbc

wbc (Wallboard Control)

A wallboard utility. Runs a full-screened iframe and some Javascript to allow for dynamic updating of wallboards. Useful if you have many clients that you would like to display metrics on.

NOTE: This is a work in progress. I am learning Go while writing this program, so please don't expect perfection.

Requirements

1. Go must be installed
2. GOPATH enviornment variable must be set
3. $GOPATH/bin must be in PATH environment variable

Usage

1. go get github.com/johnmaguire/wbc
2. wbc install
3. wbc run

If you would like to specify a custom listen address, port, or database location, you may do so with some command-line options (try wbc help install or wbc help run).

How does it work?

Calling wbc run will launch a web server on the address and port you specify (0.0.0.0:80 by default). The web server runs a simple index page, containing a full screened iframe and some nifty Javascript so as to allow control over what page the client is viewing.

The Javascript on the page connects back to the Wallboard Control websocket server and listens for commands. The server will keep the client updated with which URLs it should rotate through. Right now, clients can only rotate through a global pre-defined list of URLs. In the future, you will be able to setup a list of URLs to rotate, shuffle, or stagger (have machines show different pages) for all, or specific, clients.

At Barracuda Networks, we use Raspberry Pis hooked up to televisions to drive the wallboards. The wbc server just needs to be run somewhere that the clients can access.
