RoleName	String	No	aliyunserviceroleforactiontrail	The RAM role that ActionTrail is allowed to assume. Default value: `aliyunserviceroleforactiontrail`.
SlsProjectArn	String	No	acs:log:cn-hangzhou:159498693826****:project/trail-test	The Alibaba Cloud Resource Name (ARN) of the Log Service project to which events are to be delivered.
SlsWriteRoleArn	String	No	acs:ram::159498693826****:role/aliyunserviceroleforactiontrail	The ARN of the service-linked role that is assumed by ActionTrail to deliver events to the destination Log Service project. If you do not specify this parameter, ActionTrail creates a service-linked role to create the corresponding resource. For more information, see Manage the service-linked role. If you specify this parameter, you must grant the permissions of the service-linked role that is assumed by ActionTrail to the RAM role before you can deliver events to your Alibaba Cloud account. If you need to deliver events to other Alibaba Cloud accounts, you must attach the permission policy that is used to grant permissions related to event delivery to the RAM role. For more information about how to deliver events across Alibaba Cloud accounts, see Aggregate events across Alibaba Cloud accounts.
EventRW	String	No	All	The read/write type of the events to be delivered. Valid values: Write: write events. It is the default value. Read: read events. All: read and write events.
TrailRegion	String	No	All	The one or more regions from which the trail delivers events. The default value is All, which indicates that the trail delivers events from all regions. You can also specify specific regions. You can call the DescribeRegions operation to query all the supported regions.
MnsTopicArn	String	No	acs:mns:cn-hangzhou:1111:/topics/your-topic-name	The ARN of the Message Service (MNS) topic to which ActionTrail sends messages.
