DetectMultivariateLastAnomalyAsync(String, MultivariateLastDetectionOptions, CancellationToken)
- Source:
- AnomalyDetectorClient.cs
Detect anomalies in the last point of the request body.
public virtual System.Threading.Tasks.Task<Azure.Response<Azure.AI.AnomalyDetector.MultivariateLastDetectionResult>> DetectMultivariateLastAnomalyAsync (string modelId, Azure.AI.AnomalyDetector.MultivariateLastDetectionOptions options, System.Threading.CancellationToken cancellationToken = default);abstract member DetectMultivariateLastAnomalyAsync : string * Azure.AI.AnomalyDetector.MultivariateLastDetectionOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Response<Azure.AI.AnomalyDetector.MultivariateLastDetectionResult>>
override this.DetectMultivariateLastAnomalyAsync : string * Azure.AI.AnomalyDetector.MultivariateLastDetectionOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Response<Azure.AI.AnomalyDetector.MultivariateLastDetectionResult>>Public Overridable Function DetectMultivariateLastAnomalyAsync (modelId As String, options As MultivariateLastDetectionOptions, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Response(Of MultivariateLastDetectionResult))Parameters
- modelId
- String
Model identifier.
- options
- MultivariateLastDetectionOptions
Request of the last detection.
- cancellationToken
- CancellationToken
The cancellation token to use.
Returns
Exceptions
modelId or options is null.
modelId is an empty string, and was expected to be non-empty.
Examples
This sample shows how to call DetectMultivariateLastAnomalyAsync with required parameters.
var credential = new AzureKeyCredential("<key>");
var endpoint = new Uri("<https://my-service.azure.com>");
var client = new AnomalyDetectorClient(endpoint, credential);
var options = new MultivariateLastDetectionOptions(new VariableValues[]
{
new VariableValues("<variable>", new string[]
{
"<null>"
}, new float[]
{
3.14f
})
})
{
TopContributorCount = 1234,
};
var result = await client.DetectMultivariateLastAnomalyAsync("<modelId>", options);
Remarks
Submit a multivariate anomaly detection task with the modelId value of a trained model and inference data. The inference data should be put into the request body in JSON format. The request will finish synchronously and return the detection immediately in the response body.

[Protocol Method] Detect anomalies in the last point of the request body
- This protocol method allows explicit creation of the request and processing of the response for advanced scenarios.
- Please try the simpler DetectMultivariateLastAnomalyAsync(String, MultivariateLastDetectionOptions, CancellationToken) convenience overload with strongly typed models first.
