ACS 4.x Versus ACS 5.3 Logging
If you are familiar with the logging functionality in ACS 4.x, ensure that you familiarize yourself with
the logging functionality of ACS 5.3, which is considerably different. Table 19-4 describes the
differences between the logging functionality of ACS 4.x and ACS 5.3.

Log Types
• AAA-related logs contain information
about the use of remote access services
by users.
• Audit logs contain information about
the ACS system and activities and,
therefore, record system-related
events.
These logs are useful for
troubleshooting or audits. CSV audit
logs are always enabled, and you can
enable or disable audit logs to other
loggers. You cannot configure the audit
log content.
Audit logs can display the actual
changes administrators have made for
each user. ACS audit logs list all the
attributes that were changed for a given
user.
See Logging Categories, page 19-2.
