 == How Cumulus uses the daily log ==
-*Cumulus is frequently reading observations from your weather station. When it is restarted, depending on the make of weather station, it may read observations from the station's log into the Cumulus monthly log, otherwise the observations in the station's current measurements holder at the Cumulus logging interval are what gets written into the monthly log.
