Hey all, I’m running into an issue where a device is not marked as down (red in the threshold) when there is not any data. I do have the ‘No Value’ setting set to 100, and the threshold for a red ‘bad’ status is 99.
So when our monitoring software reports no value for the sensor, Grafana, as expected, fills it in as 100.
My issue is that it’s not reflected on the state timeline. In the above screenshot, the ‘ignore me’ device has been offline for about fifteen minutes, but Grafana reports it as up. Can you spot anything I’m doing wrong? Panel JSON is as follows:
