New-VSIoTEventsDetectorModel
New-VSIoTEventsDetectorModel
SYNOPSIS
Adds an AWS::IoTEvents::DetectorModel resource to the template. The AWS::IoTEvents::DetectorModel resource creates a detector model. You create a detector model (a model of your equipment or process using states. For each state, you define conditional (Boolean logic that evaluates the incoming inputs to detect significant events. When an event is detected, it can change the state or trigger custom-built or predefined actions using other AWS services. You can define additional events that trigger actions when entering or exiting a state and, optionally, when a condition is met. For more information, see How to Use AWS IoT Events: https://docs.aws.amazon.com/iotevents/latest/developerguide/how-to-use-iotevents.html in the AWS IoT Events Developer Guide.

DESCRIPTION
Adds an AWS::IoTEvents::DetectorModel resource to the template. The AWS::IoTEvents::DetectorModel resource creates a detector model. You create a detector model (a model of your equipment or process using states. For each state, you define conditional (Boolean logic that evaluates the incoming inputs to detect significant events. When an event is detected, it can change the state or trigger custom-built or predefined actions using other AWS services. You can define additional events that trigger actions when entering or exiting a state and, optionally, when a condition is met.

Note
When you successfully update a detector model (using the AWS IoT Events console, AWS IoT Events API or CLI commands, or AWS CloudFormation all detector instances created by the model are reset to their initial states. (The detector’s state, and the values of any variables and timers are reset.
When you successfully update a detector model (using the AWS IoT Events console, AWS IoT Events API or CLI commands, or AWS CloudFormation the version number of the detector model is incremented. (A detector model with version number 1 before the update has version number 2 after the update succeeds.
If you attempt to update a detector model using AWS CloudFormation and the update does not succeed, the system may, in some cases, restore the original detector model. When this occurs, the detector model’s version is incremented twice (for example, from version 1 to version 3 and the detector instances are reset.
Also, be aware that if you attempt to update several detector models at once using AWS CloudFormation, some updates may succeed and others fail. In this case, the effects on each detector model’s detector instances and version number depend on whether the update succeeded or failed, with the results as stated.
PARAMETERS
-LogicalId
The logical ID must be alphanumeric (A-Za-z0-9) and unique within the template. Use the logical name to reference the resource in other parts of the template. For example, if you want to map an Amazon Elastic Block Store volume to an Amazon EC2 instance, you reference the logical IDs to associate the block stores with the instance.

-Key
The value used to identify a detector instance. When a device or system sends input, a new detector instance with a unique key value is created. AWS IoT Events can continue to route input to its corresponding detector instance based on this identifying information. This parameter uses a JSON-path expression to select the attribute-value pair in the message payload that is used for identification. To route the message to the correct detector instance, the device must send a message payload that contains the same attribute-value.

-DeletionPolicy
With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted. You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy attribute, AWS CloudFormation deletes the resource by default.
To keep a resource when its stack is deleted, specify Retain for that resource. You can use retain for any resource. For example, you can retain a nested stack, S3 bucket, or EC2 instance so that you can continue to use or modify those resources after you delete their stacks.
You must use one of the following options: “Delete”,”Retain”,”Snapshot”
Type: String
Parameter Sets: (All)
Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-UpdateReplacePolicy
Use the UpdateReplacePolicy attribute to retain or (in some cases) backup the existing physical instance of a resource when it is replaced during a stack update operation.
When you initiate a stack update, AWS CloudFormation updates resources based on differences between what you submit and the stack’s current template and parameters. If you update a resource property that requires that the resource be replaced, AWS CloudFormation recreates the resource during the update. Recreating the resource generates a new physical ID. AWS CloudFormation creates the replacement resource first, and then changes references from other dependent resources to point to the replacement resource. By default, AWS CloudFormation then deletes the old resource. Using the UpdateReplacePolicy, you can specify that AWS CloudFormation retain or (in some cases) create a snapshot of the old resource.
For resources that support snapshots, such as AWS::EC2::Volume, specify Snapshot to have AWS CloudFormation create a snapshot before deleting the old resource instance.
You can apply the UpdateReplacePolicy attribute to any resource. UpdateReplacePolicy is only executed if you update a resource property whose update behavior is specified as Replacement, thereby causing AWS CloudFormation to replace the old resource with a new one with a new physical ID. For example, if you update the Engine property of an AWS::RDS::DBInstance resource type, AWS CloudFormation creates a new resource and replaces the current DB instance resource with the new one. The UpdateReplacePolicy attribute would then dictate whether AWS CloudFormation deleted, retained, or created a snapshot of the old DB instance. The update behavior for each property of a resource is specified in the reference topic for that resource in the AWS Resource and Property Types Reference. For more information on resource update behavior, see Update Behaviors of Stack Resources.
The UpdateReplacePolicy attribute applies to stack updates you perform directly, as well as stack updates performed using change sets.
Note Resources that are retained continue to exist and continue to incur applicable charges until you delete those resources. Snapshots that are created with this policy continue to exist and continue to incur applicable charges until you delete those snapshots. UpdateReplacePolicy retains the old physical resource or snapshot, but removes it from AWS CloudFormation’s scope.
UpdateReplacePolicy differs from the DeletionPolicy attribute in that it only applies to resources replaced during stack updates. Use DeletionPolicy for resources deleted when a stack is deleted, or when the resource definition itself is deleted from the template as part of a stack update.

-DependsOn
With the DependsOn attribute you can specify that the creation of a specific resource follows another. When you add a DependsOn attribute to a resource, that resource is created only after the creation of the resource specified in the DependsOn attribute.
This parameter takes a string or list of strings representing Logical IDs of resources that must be created prior to this resource being created.
Type: String[]
Parameter Sets: (All)
Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False

-Metadata
The Metadata attribute enables you to associate structured data with a resource. By adding a Metadata attribute to a resource, you can add data in JSON or YAML to the resource declaration. In addition, you can use intrinsic functions (such as GetAtt and Ref), parameters, and pseudo parameters within the Metadata attribute to add those interpreted values.
You must use a PSCustomObject containing key/value pairs here. This will be returned when describing the resource using AWS CLI.

-UpdatePolicy
Use the UpdatePolicy attribute to specify how AWS CloudFormation handles updates to the AWS::AutoScaling::AutoScalingGroup resource. AWS CloudFormation invokes one of three update policies depending on the type of change you make or whether a scheduled action is associated with the Auto Scaling group.
You must use the “Add-UpdatePolicy” function here.
