Getting started

Install the package

Install the Azure Anomaly Detector client library for .NET with NuGet:

dotnet add package Azure.AI.AnomalyDetector --version 3.0.0-preview.2

Prerequisites

For more information about creating the resource or how to get the location and sku information see here.

Authenticate the client

In order to interact with the Anomaly Detector service, you'll need to create an instance of the AnomalyDetectorClient class. You will need an endpoint and an API key to instantiate a client object.

Get API Key

You can obtain the endpoint and API key from the resource information in the Azure Portal.

Alternatively, you can use the Azure CLI snippet below to get the API key from the Anomaly Detector resource.

az cognitiveservices account keys list --resource-group <your-resource-group-name> --name <your-resource-name>

Create AnomalyDetectorClient with AzureKeyCredential

Once you have the value for the API key, create an AzureKeyCredential. With the endpoint and key credential, you can create the AnomalyDetectorClient:

string endpoint = "<endpoint>";
string apiKey = "<apiKey>";
var credential = new AzureKeyCredential(apiKey);
var client = new AnomalyDetectorClient(new Uri(endpoint), credential);

Create AnomalyDetectorClient with Azure Active Directory Credential

AzureKeyCredential authentication is used in the examples in this getting started guide, but you can also authenticate with Azure Active Directory using the Azure Identity library. Note that regional endpoints do not support AAD authentication. Create a custom subdomain for your resource in order to use this type of authentication.

To use the DefaultAzureCredential provider shown below, or other credential providers provided with the Azure SDK, please install the Azure.Identity package:

Install-Package Azure.Identity

You will also need to register a new AAD application and grant access to Anomaly Detector by assigning the "Cognitive Services User" role to your service principal.

Set the values of the client ID, tenant ID, and client secret of the AAD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET.

string endpoint = "<endpoint>";
var client = new AnomalyDetectorClient(new Uri(endpoint), new DefaultAzureCredential());

Troubleshooting

Setting up console logging

The simplest way to see the logs is to enable the console logging. To create an Azure SDK log listener that outputs messages to console use the AzureEventSourceListener.CreateConsoleLogger method.

// Setup a listener to monitor logged events.
using AzureEventSourceListener listener = AzureEventSourceListener.CreateConsoleLogger();

To learn more about other logging mechanisms see Diagnostics Samples.
