-- | Contains the metadata about a type of event that is reported by Health.
-- The @EventType@ shows the category, service, and the event type code of
-- the event. For example, an @issue@ might be the category, @EC2@ the
-- service, and @AWS_EC2_SYSTEM_MAINTENANCE_EVENT@ the event type code.
--
-- You can use the
-- <https://docs.aws.amazon.com/health/latest/APIReference/API_DescribeEventTypes.html DescribeEventTypes>
-- API operation to return this information about an event.
--
-- You can also use the Amazon CloudWatch Events console to create a rule
-- so that you can get notified or take action when Health delivers a
-- specific event to your Amazon Web Services account. For more
-- information, see
-- <https://docs.aws.amazon.com/health/latest/ug/cloudwatch-events-health.html Monitor for Health events with Amazon CloudWatch Events>
-- in the /Health User Guide/.
