I’m very new to grafana - as in about an hour ago. My org has a windows server down. I was given the login to the grafana display - from a rhel 8 server running prometheus (or does the data for all of our servers come from the node exporter to prometheus, which reports to grafana - still figuring that out). Anyway a server is down and the display goes from red to green to red back to green. I go in to edit that panel and originally there was no value under “Critical” in the “threshold” section. I put a 0 in there and the panel went red. But after a few minutes it goes right back to green. Yet the server is still down. I can’t seem to figure out what’s causing that. Can anyone point me in the right direction?
I can’t find any difference in the JSON for this down server and any of the other Windows servers configured. Could that mean that none of them will display correctly?
