 Grouping Attributes in Reports: When creating reports in FortiSIEM, certain attributes can be grouped to summarize and organize the data.

 Unique Attributes: Attributes that are unique for each event cannot be grouped because they do not provide a meaningful aggregation or summary.

 Red Highlighting Explanation: The red highlighting in the exhibit indicates attributes that cannot be grouped together due to their unique nature. These unique attributes includeEvent Receive Time,Reporting IP,Event Type,Raw Event Log, andCOUNT(Matched Events).

 Attribute Characteristics:

Event Receive Timeis unique for each event.

Reporting IPandEvent Typecan vary greatly, making grouping them impractical in this context.

Raw Event Logrepresents the unprocessed log data, which is also unique.

COUNT(Matched Events)is a calculated field, not suitable for grouping.
