Extend Audit Backlog Limit for the Audit Daemon in zIPL
Medium Severity
To improve the kernel capacity to queue all log events, even those which start prior to the audit daemon, check that all boot entries in
/boot/loader/entries/*.conf
have
audit_backlog_limit=8192
included in its options.
To ensure that new kernels and boot entries continue to extend the audit log events queue, add
audit_backlog_limit=8192
to
/etc/kernel/cmdline
.
