Generic Fields (3)
These are common fields that appear across multiple namespaces. They represent attributes that are inherited or reused from a global schema— things like timestamps, unique identifiers, user IDs, or status codes that every namespace needs. By sharing these fields, we ensure consistency and make it easy to run cross-namespace searches and reports.

|---|---|---|
gen.hostname Normalized hostname of the system generating the log. | file.hostname | text_general |
gen.file.name File name associated with the event. | file.path | strings |
gen.file.path Full file path associated with the event. | file.path | strings |
