.. py:method:: Health.Client.describe_event_aggregates(**kwargs)

  

  Returns the number of events of each event type (issue, scheduled change, and account notification). If no filter is specified, the counts of all events in each category are returned.

   

  .. note::

    

    This API operation uses pagination. Specify the ``nextToken`` parameter in the next request to return more results.
