예
[ceph: root@host01 /]# ceph config set mgr mgr/cephadm/log_to_cluster_level debug [ceph: root@host01 /]# ceph -W cephadm --watch-debug [ceph: root@host01 /]# ceph -W cephadm --verbose
디버깅 수준을 기본
info로 반환 :예
[ceph: root@host01 /]# ceph config set mgr mgr/cephadm/log_to_cluster_level info
최근 이벤트를 보려면 다음 명령을 실행합니다.
예
[ceph: root@host01 /]# ceph log last cephadm
이러한 이벤트는 모니터 호스트의 ceph.cephadm.log 파일 및 모니터 데몬의 stderr에도 기록됩니다.
