Debug Window Understanding

Hello everyone,

If there is already some documentation available on this then I do apologize as I could not find it in the forum or anywhere else yet.

In the debug window of mission planner, there are boxes in the far right showing all the modules running in mission planner and the flight controller.

What I am having difficulty is in that I cannot seem to understand what the status of each means.
For example, for the battery: It shows it is enabled, it is present, and that it is OK.
But for the proximity: It shows it is enabled, it is present, and that it is BAD.

If anyone can share their info or leave a link to an already discussed topic then that would be very helpful.

Thanks
