I’m using influxdb in combination with Openhab to store sensor readings. 1 reading every 10mins. For visualization I’m using Grafana. When I installed a new sensor I noticed that the readings of the old measurements were not shown. So I set the Date Selection 2 months back and saw that the readings stopped being written. Is there a limit of entries per measurement?
@andy_k There’s no limit for measurement, the series should keep increasing. Is it possible the points were dropped as part of a retention policy?
If the old readings are still there I would guess that’s not the retention policy dropping them but rather they are not written in anymore? Do they happen to have all the exact same tags as the new sensor? That would overwrite the values
