A macro in FortiAnalyzer primarily defines what?

In FortiAnalyzer, a macro is utilized to define which data is to be selected from logs when generating reports. Macros act as placeholders or variables that can represent specific criteria or values, allowing for dynamic data selection based on user-defined parameters. This enables more customized reporting by allowing users to specify log fields or conditions that should be included in the report, ensuring that the data extracted is relevant to the analysis being performed.

While the other options pertain to different aspects of report generation—like the visual layout, export settings, and scheduling—macros specifically focus on the data selection process, which is essential for tailoring reports according to the specific informational needs of the user or organization. By using macros effectively, users can streamline their reporting processes and enhance the clarity and relevance of the information presented in their reports.
