GroupBy analyzer followed by aggregate analyzer can be used to this
requirement. In the group by use time based grouping with required
granularity "DAY, MONTH, YEAR" etc.
<groupBy>
<time name='time' granularity='MONTH'/>
</groupBy>
See [1]. These kind of aggregations would become much easy with Hive based
analytics in the future.
