# EventType
<a name="API_EventType"></a>

Contains the metadata about a type of event that is reported by AWS 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 [DescribeEventTypes](https://docs.aws.amazon.com/health/latest/APIReference/API_DescribeEventTypes.html) 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 AWS Health delivers a specific event to your AWS account. For more information, see [Monitor for AWS Health events with Amazon CloudWatch Events](https://docs.aws.amazon.com/health/latest/ug/cloudwatch-events-health.html) in the * AWS Health User Guide*.
