Data housekeeping



I know the options for Historic Data Purging. Here I find the setting Historic Sensor Data which is by default 365 days. Does that mean that PRTG will keep every measurement for this period of time or is there also an option for taking averages from measurements after a while. For example: - Store every measurement for 30 days (60 second sensor interval) - After 30 days, recalculate the measurements to averages of 15 minute interval - After 180 days, recalculate the measurements to averages of 1 hour interval

Ofcourse which the result that it uses less space?

PRTG will store all historic data for 365 days and will purge the oldest day after this time. There is no recalculation to another average, the interval will persist for the 365 days.
