What is the function of the Notification Editor?

The Notification Editor's primary role is to build Triggered Metric Events, which involves setting up notifications based on specific conditions or thresholds related to metrics. This functionality allows users to define when and how they would like to be alerted regarding particular events or changes in the data that are significant or warrant attention. By customizing the triggers for notifications, users can ensure that they remain informed about critical situations impacting their metrics in real time, thereby fostering timely responses and proactive management.

In contrast, the other functions described, such as creating and editing metric definitions, managing user permissions, and storing actual metric data, pertain to different aspects of a data management system and do not involve the direct creation or configuration of notifications based on metric events. This distinction clarifies why the correct answer centers on the Notification Editor's capability to facilitate Triggered Metric Events.
