D

Smart Detection automatically warns you of potential performance problems and failure anomalies in your web application. It performs proactive analysis of the telemetry that your app sends to Application Insights. If there is a sudden rise in failure rates, or abnormal patterns in client or server performance, you get an alert.

The correct answer to the question is D. Smart Detection.

Explanation:

Azure Application Insights is a powerful tool for monitoring the health and performance of Azure web apps. It provides various features and functionalities, including alerts, dashboards, and reports, to help developers and administrators keep track of the app's performance and identify potential issues.

One of the features of Azure Application Insights is Smart Detection, which is designed to detect and alert on performance anomalies and failures. Smart Detection uses machine learning algorithms to analyze telemetry data from various sources, including logs, metrics, and traces, and identifies patterns and trends that could indicate potential issues.

Smart Detection provides several types of alerts, including:

  1. Performance anomalies: These alerts are triggered when there is a sudden increase in response time, error rate, or other performance metrics.

  2. Failure anomalies: These alerts are triggered when there is a sudden increase in the number of exceptions, crashes, or other types of failures.

  3. Dependency failures: These alerts are triggered when there is a sudden increase in the number of failures in the app's dependencies, such as databases, APIs, or other services.

To set up Smart Detection alerts, you need to go to the Azure portal, select the web app you want to monitor, and navigate to the Smart Detection section under the Monitoring tab. From there, you can enable the alerts you want to receive and configure the alert thresholds and notification settings.

In summary, if you need to ensure that an alert is sent when an Azure web app has a sudden rise in performance issues and failures, you should use Smart Detection in Azure Application Insights.
