I’ve tried asking in the influxdb forums but haven’t received a response yet, so maybe the grafana community knows the answer. I’m wondering if there is a way to forcast/predict when a value will hit zero over time? In particular, I’m interested in forcasting disk usage, or more specifically, disk space free. I looked at the documentation on holt-winters forcasting, but I can’t seem to make that work. Basically I want to generate a graph that will show when disk-space free will hit zero, using the existing data already recorded (disk used, in bytes). Is holt winters suitable for this? or is there a different function available to accomplish this? Or is it not possible at all?
