Which feature allows viewing log data for a group of devices as if they were one?

The ability to view log data for a group of devices as if they were one is provided by the feature known as "run reports on log groups." This function consolidates log information from multiple devices, allowing administrators to analyze the data collectively. By creating reports that encompass various devices, users can efficiently review security events, performance metrics, and other significant information in one consolidated view. This is particularly valuable for organizations with numerous devices, as it simplifies analysis and monitoring.

In contrast, aggregate logging typically involves the collection and summarization of logs but does not inherently offer a unified view like report generation does. The unified reporting interface is a feature that helps in presenting data from diverse sources, but the key aspect of viewing log data grouped together is more precisely described by running reports on log groups. Single device management focuses on the administration of individual devices without offering a collective analysis of multiple devices. Thus, the most accurate and contextually relevant choice for combining and viewing log data from a group of devices is to run reports on log groups.
