Issue #16 new
If (e.g. in testcode) a table is created, then it is > aggregation_interval before an entry is made it's possible for _macro_aggregate to be called with points being an empty list.
This causes the log to fail - as min() raises a value error.
def _macro_aggregate(self): """Perform aggregation every aggregation_interval""" # aggregate if len(points) > 0: points = self.current_point_list interval = (self.current_point_time - self.last_aggregation_time) / 60.0 self.log.info("%s: interval=%s min=%s max=%s average=%s", self.name, round(interval), min(points), max(points), average(points)) #reset self.current_point_list =  self.last_aggregation_time = int(time())
