Configure the operating system to initiate an action to notify the SA and ISSO (at a minimum) when allocated audit record storage volume reaches 75 percent of the repository maximum audit record storage capacity.
Set the value of the "space_left" keyword in "/etc/audit/auditd.conf" to 25 percent of the partition size.
space_left = 25%
Reload the auditd daemon to apply changes made to the "/etc/audit/auditd.conf" file.
$ sudo service auditd restart
