Synopsis

Calls the Amazon CloudWatch Evidently EvaluateFeature API operation.

Syntax

Get-CWEVDFeatureEvaluation
-EntityId <String>
-EvaluationContext <String>
-Feature <String>
-Project <String>
-Select <String>
-ClientConfig <AmazonCloudWatchEvidentlyConfig>

Description

This operation assigns a feature variation to one given user session. You pass in an entityID that represents the user. Evidently then checks the evaluation rules and assigns the variation. The first rules that are evaluated are the override rules. If the user's entityID matches an override rule, the user is served the variation specified by that rule. If there is a current launch with this feature that uses segment overrides, and if the user session's evaluationContext matches a segment rule defined in a segment override, the configuration in the segment overrides is used. For more information about segments, see CreateSegment and Use segments to focus your audience. If there is a launch with no segment overrides, the user might be assigned to a variation in the launch. The chance of this depends on the percentage of users that are allocated to that launch. If the user is enrolled in the launch, the variation they are served depends on the allocation of the various feature variations used for the launch. If the user is not assigned to a launch, and there is an ongoing experiment for this feature, the user might be assigned to a variation in the experiment. The chance of this depends on the percentage of users that are allocated to that experiment. If the experiment uses a segment, then only user sessions with evaluationContext values that match the segment rule are used in the experiment. If the user is enrolled in the experiment, the variation they are served depends on the allocation of the various feature variations used for the experiment. If the user is not assigned to a launch or experiment, they are served the default variation.

Parameters

-ClientConfig <AmazonCloudWatchEvidentlyConfig>
Amazon.PowerShell.Cmdlets.CWEVD.AmazonCloudWatchEvidentlyClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-EntityId <String>
An internal ID that represents a unique user of the application. This entityID is checked against any override rules assigned for this feature.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-EvaluationContext <String>
A JSON object of attributes that you can optionally pass in as part of the evaluation event sent to Evidently from the user session. Evidently can use this value to match user sessions with defined audience segments. For more information, see Use segments to focus your audience.If you include this parameter, the value must be a JSON object. A JSON array is not supported.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Feature <String>
The name of the feature being evaluated.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Project <String>
The name or ARN of the project that contains this feature.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.CloudWatchEvidently.Model.EvaluateFeatureResponse). Specifying the name of a property of type Amazon.CloudWatchEvidently.Model.EvaluateFeatureResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesSK, SecretAccessKey
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesST

Outputs

Amazon.CloudWatchEvidently.Model.EvaluateFeatureResponse
This cmdlet returns an Amazon.CloudWatchEvidently.Model.EvaluateFeatureResponse object containing multiple properties. The object can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
