Configure auditd space_left threshold to 25 percent

auditd-space-left-percent · RHEL ≥ 8 · 1 impl

Description

The auditd space_left parameter must be configured to notify the system administrator when the audit log storage volume has 25 percent or less capacity remaining.

Rationale

Configuring a space_left threshold ensures administrators are alerted before audit storage is exhausted. A 25 percent threshold provides adequate warning time to take corrective action.
