def _parse_datapoints(self, parsed_duration, parsed_resolution, limit):
return self.datapoints_parser.parse(parsed_duration, parsed_resolution, limit)<EOL>
Parse the number of datapoints of a query.
This can be calculated from the given duration and resolution of the query.
E.g. if the query has a duation of 2*60*60 = 7200 seconds and a resolution of 10 seconds
then the number of datapoints would be 7200/10 => 7200 datapoints.
