Alerts must be automatically generated to notify the administrator when log storage reaches seventy-five percent or more of its maximum capacity.

Description
Configuring the network device or syslog server to provide alerts to the administrator in the event of modification or audit log capacity being exceeded ensures administrative staff is aware of critical alerts. Without this type of notification setup, logged audits and events could potentially fill to capacity, causing subsequent records to not be recorded and dropped without any knowledge by the administrative staff. Other unintended consequences of filling the log storage to capacity may include a denial of service of the device itself without proper notification.
