Description |
---|
The audit service must be configured to require a minimum percentage of free disk space to run. This ensures that audit will notify the administrator that action is required to free up more disk space for audit logs. When "minfree" is set to 25 percent, security personnel are notified immediately when the storage volume is 75 percent full and are able to plan for audit record storage capacity expansion. |
