Automatic color change on objects

Hi, I’m trying to figure out how to solve the following : I want to create some small bubbles which should change their color when a certain condition is met : for example (please see attached figure), I’m having bubbles named 1/0/1 etc, switch interface number. I want this bubbles to be green, as long as that interface has status “up” and when the interface goes down, to change the color to red. I know i can use the probes section on the devices but i would love to have the status of important up-links straight in the main network map.
Thanks in advance
