Goal
The goal of this project is to display Nagios Server's status on RGB Led Matrix.
I have 4 Led Matrix, the idea is to create one box per matrix with 230V connector and Data IN/OUT So we can decide if we want to use 1-4 Matrix
Data flow
- Nagios server get servers status and store data into MySQL Database with XXXX plugin
- Perl script on Alix (PC Engine) is getting data from MySQL and transmit data by JSON to mbed (by USB).
- mbed get json's data from Alix and display to Led Matrix
- Led matrix display Servers status :-)
Used componment
- 1 mbed NXP LPC1768 [1]
- 2 RGB Led Matix (64x32) for display
- 1 ALix 2d13 for getting Nagios status and sending to MBED
Hardware pieces listing (per matrix box)

Perl script on ALIX
This perl script is getting data form MySQL to send to mbed. It run every minutes by cron.
Requiert Perl modules

Source code
The source code is accessible from there
JSON data example
{
"action": "insert",
"id":0,
"text": "server1.domain.ch",

"position_y": 5,
"position_lenght": 78,
"scroll_speed": 255,
"red": 3,
"green": 0,
"blue": 2
}
| Field | Value | Description |
|---|---|---|
| action | string: insert,delete,modify | used to insert,delete,modify data vector on mbed |
| id | integer | id of data to modify,delete |
| text | string | text to display |
| position_x | integer | X position of text area |
| position_y | integer | Y position of text area |
| position_lenght | integer | lenght of text area |
| scroll_speed | integer 0-255 | scrolling speed |
| red | integer 0-4 | RGB value |
| green | integer 0-4 | RGB value |
| blue | integer 0-4 | RGB value |
