In anomaly detection, which metric can trigger an alert if it drops below a certain percentage?

In anomaly detection, the metric that can trigger an alert if it drops below a certain percentage is closely associated with monitoring performance and user experience metrics. Traffic Drops is particularly significant in this context because it directly reflects the volume of user interactions with a system. If the traffic suddenly drops below a certain threshold, it may indicate a potential issue, such as a failed deployment, downtime, or even an external factor affecting user access to the application. Monitoring traffic allows organizations to quickly identify severe changes in user behavior and respond promptly, thereby safeguarding overall application performance and stability.

The other metrics, while important, serve different functions. Response Time usually measures how quickly the application responds to user actions but does not necessarily indicate an immediate drop in user activity. User Engagement gauges how actively users are interacting with the application, but it can be more subjective and less quantifiable than direct traffic metrics. Finally, Session Duration focuses on how long users stay engaged but doesn’t capture sudden drops in user visits or engagement levels. Therefore, Traffic Drops stands out as the most critical metric for alerting on significant deviations in user activity.
