Concept

Some values are worth having but nobody logs them, because they are derived from values that are logged. Computing them consistently on every search is what makes them behave like real fields.

Why C

Splunk states that calculated fields are fields added to events at search time that perform calculations with the values of two or more fields already present in those events.

Source

Calculated fields are fields added to events at search time that perform calculations with the values of two or more fields already present in those events. Use calculated fields as a shortcut for performing repetitive, long, or complex transformations using the eval command.
