Navigate to and open:

/etc/audit/auditd.conf

Ensure the "space_left" and "space_left_action" lines are uncommented and set to the following:

space_left = 25%
space_left_action = SYSLOG

At the command line, run the following command:

# pkill -SIGHUP auditd

Check Contents

At the command line, run the following command to verify auditd is alerting when low disk space is detected:
