When a query is run, the Field Summary panel lists the CEF and non-CEF fields that occur in matching events and the number of unique values for each in those events. This panel is only displayed for queries that do not generate charts. If a peer search is performed, the summarized field values include counts from peer Loggers.
Field Summary displays additional information such as events containing the field, available charts, and top and bottom ten values. Multiple events can be opened simultaneously and moved at your convenience.
The Field Summary panel contains two sections: Selected Fields and Discovered Fields. The Selected Fields section lists the CEF fields, while the Discovered Fields section lists the non-CEF fields discovered in raw events.
