No server monitoring from Foglight?

This question has been hounding me and figured I'd ask it here but keep searching for an answer.

One of my sql servers is running fine but Foglight' dashboard is showing dashes 9apps where the system utilization\up since are at.  I can ping it from the agent manager, and it is gathering sql server PI data as well.

What do I need to check or change to get this to start gathering OS information?https://snaptube.cam/
