Audit Log Reference
Published July 28, 2026 | Last modified August 12, 2026
Overview
Use this reference to look up the fields F5 Distributed Cloud Services writes to audit logs. Audit logs record actions performed on objects. F5 stores them on the Global Controller with longer retention than application logs.
Types of audit logs
Distributed Cloud Services generates two types of audit logs: success and failure. The log information is stored in JSON format. Some information is unique to each type of log, and other information is present in both.
Important: Don't edit or take action on keys marked For use by F5 only in the Description column. F5 will remove these keys in a future release.
