New question #294817 on Graphite: https://answers.launchpad.net/graphite/+question/294817
Hi, I noticed the calculation for the interval from the timestamp for updating a data point is different from the calculation for fetching data points. When the whisper update a data point, the interval is t - (t % archive['secondsPerPoint']) https://github.com/graphite-project/whisper/blob/d5dc6a07d4bfe13a14db74b595740cdc22d18531/whisper.py#L572-L593 def file_update(fh, value, timestamp): # ...(snip)... myInterval = timestamp - (timestamp % archive['secondsPerPoint']) However when the whisper fetches datapoints, the interval is t - (t % archive['secondsPerPoint']) + archive['secondsPerPoint'] https://github.com/graphite-project/whisper/blob/d5dc6a07d4bfe13a14db74b595740cdc22d18531/whisper.py#L814-L821 def __archive_fetch(fh, archive, fromTime, untilTime): # ...(snip)... fromInterval = int(fromTime - (fromTime % archive['secondsPerPoint'])) + archive['secondsPerPoint'] untilInterval = int(untilTime - (untilTime % archive['secondsPerPoint'])) + archive['secondsPerPoint'] Could you tell me why they are different?
