Hey there.
I ordered a traffic light for a desk. It can be controlled by a linux client. I have all mission critical things on a nagvis map. I would like to map the state of the map with the traffic light:
if the specific map is red in the checkmk side bar, the traffic light should turn to red as well. How can I request the overall state of a nagvis map (as the side bar is doing)?
Hint: There is already one traffic light solution, but controlled with GPIOs and based on contact_groups. Ronny did a great job here: Network attached Traffic-Light style status display for CheckMK - Guide
Announcement: if I have a working solution, I post this here. Maybe we can collect different solutions for traffic light installations.
