ko_center is a PHP-based data center control panel that transforms complex rack-level infrastructure into an intuitive, visual dashboard. Every server rack /tracking item in your data center is represented by an LED indicator floor-plan views give administrators an at-a-glance picture of entire facility health no login required for features monitoring. separate floor-plan views are also avalible |

|
Yellow = warning
|
|
Red = requires attention
|
|
Red - fast blinks = requires immediate elevated attention
|
|
Blink Speed indicates severity level
|

Hardware Configuration Settings can be adjusted manually or automatically based on sensor output and other criteria
|
|
LEDS can be manualy or auto-set to green when server issues are resolved |
|
yellow if issues are still pending or red with faster blink speed indicating
problem escalation
|
|
can be configure with Sensor-driven status updates eliminate manual polling
|
|
LEDS can also be configured to trigger actions such as sending email, running custom scripts
