Which of the following best describes a macro?

A macro, in the context of systems like FortiAnalyzer, refers to a way to define the data selections from logs. It enables users to create custom filters or queries that can streamline the process of analyzing log data by focusing on specific entries or patterns of interest. This functionality is particularly useful when dealing with large datasets, allowing users to quickly isolate relevant information, apply consistent criteria, and generate reports without manually sifting through extensive log records.

While other options discuss different functionalities—such as logging user activities, automating processes, or graphic styling—none of these accurately capture the essence of a macro's role in log management. A macro specifically aids in the organized selection and filtering of data, enhancing the efficiency and effectiveness of log analysis and reporting within FortiAnalyzer.
