* It reads the daily summary log (dayfile.txt) and uses the rainfall totals for each day stored in the daily summary log to calculate the rainfall for this month, and this year/season (see [[FAQ#Where_does_Cumulus_get_its_this_month_and_this_year_rainfall_totals_from.3F|this Cumulus 1 FAQ]])
* Thus you must not have another process attempting access to the daily log when Cumulus is re-starting.
