경보 조치 감사

경보 조치로 실행되는 워크플로우에서는 audit 함수를 사용하여 감사 로그 항목을 생성할 수 있습니다. audit 함수를 통해 관련된 모든 디버깅 정보를 감사 로그에 생성해 넣는 것이 좋습니다. 예를 들어, 다음은 클러스터화된 상태에 있는 경우 페일오버를 실행하지만 재부트하기 위해 모든 오류를 감사하는 워크플로우입니다.

                * To failover, we first confirm that clustering is configured
                * and that we are in the clustered state.  We then reboot,
                * which will force our peer to takeover.  Note that we're
                * being very conservative by only rebooting if in the
                * AKCS_CLUSTERED state:  there are other states in which it
                * may well be valid to failback (e.g., we are in AKCS_OWNER,
                * and our peer is AKCS_STRIPPED), but those states may also
                * indicate aberrent operation, and we therefore refuse to
                * failback.  (Even in an active/passive clustered config, a
                * FAILBACK should always be performed to transition the
                * cluster peers from OWNER/STRIPPED to CLUSTERED/CLUSTERED.)
