Cisco CLI 명령어, show process cpu (history) 명령 및 데몬별 cpu 점유 확인, 히스토리 확인
귀하신분 2011. 12. 26. 14:09Cisco CLI 명령어, show process cpu (history) 명령 및 데몬별 cpu 점유 확인, 히스토리 확인
거의 모든 라우터나 스위치를 생산하는 회사나 업체들은 Cisco의 CLI 명령을 따라하기 마련입니다.
네트웍 관리자들은 거의 모두가 Cisco 의 CCNA를 시작하여 CCNP 또는 CCIE 등의 3단계 등급에 따른 시험을 치루어 자격증을 따기 때문에 관리자들의 입장에서 보면 Cisco 의 명령들이 손과 눈에 익숙하기 때문입니다.
네트웍 관리자들은 거의 모두가 Cisco 의 CCNA를 시작하여 CCNP 또는 CCIE 등의 3단계 등급에 따른 시험을 치루어 자격증을 따기 때문에 관리자들의 입장에서 보면 Cisco 의 명령들이 손과 눈에 익숙하기 때문입니다.
물론 쥬니퍼(Juniper)나 HP, 리버스톤(River Stone) 등의 경우에는 그에 따르지는 않습니다.
오늘은 그 명령어 중 라우터나 스위치의 CPU 상태를 확인하고, 그 히스토리까지 확인할 수 있는 show process 명령에 대해 알아보도록 하겠습니다.
아래는 현재 운용 중인 C3750 L3 스위치에서 확인한 show process 입니다.
C3750#show process
CPU utilization for five seconds: 5%/0%; one minute: 6%; five minutes: 5%

단지 show process 명령만 실행하여 모든 실행중인 process 와 데몬을 확인하고 cpu의 점유 및 사용 상태를 확인할 수 있습니다.
show process cpu 의 명령으로 cpu에 관여된 프로세서들을 확인하는 방법과 동일한 방법입니다.
여기서 가장 중요한 부분을 보시게 되는데요,
가장 윗줄에 위치하는 cpu utilization 의 시간별 통계치 입니다.
CPU utilization for five seconds: 5%/0%; one minute: 6%; five minutes: 5%
CCNA 시험 칠 때 단골 메뉴라고 할 수 있죠~^^
처음 나오는 5%/0% 는 cpu의 5초 평균값에 대한 사용량을 나타나내어 주고 / 뒷부분의 수치는 인터럽트로 인한 cpu 사용량을 나타내어 줍니다.
그리고 1분 평균 6%, 5분 평균 5% 의 cpu 사용량을 확인할 수 있습니다.
memory 의 점유율을 확인하는 명령은 show memory (메모리 주소와 매칭되어 보여짐) 외에 show process memory 의 명령으로 확인 가능합니다.
show process cpu history 명령으로 시간대별 (per second, per minute, per houe) 로 cpu 점유율을 텍스트형 그래프로 확인하실 수 있습니다.
아래는 그 화면을 캡쳐한 것으로 총 3개의 그래프가 나타나게 됩니다.

per second 에 대한 cpu 점유율은 10% 이하로 양호한 상태를 보였지만, per hour 에 대한 cpu 점유율은 최대 70% 까지 치솟은 것을 볼 수 있습니다.
이는 현재 구동 중인 dynamic routing protocol 의 성능 대비 과부하로 인한 문제일 수도 있으며, 트래픽의 과부하 등, 인위적인 트래픽 발생에 따른 cpu 상승 (extended ping test), IOS 버그 등의 여러가지 문제로 인하여 나타날 수도 있습니다.
캡쳐화면에 나타나는 cpu 상승의 원인은 인위적인 ping 테스트로 인한 일시적 cpu 상승 현상입니다. 회선 점검을 위해 어제부터 계속해서 확장 ping 테스트를 감행했던 이유에서 입니다.
C3750 이라는 조금은 급이 낮은 장비라서 많은 개수의 확장 ping 테스트 시 cpu 상태를 모니터링하신 후 진행해야 할 것입니다.
개인적 경험으로는 C6506, C6509 급 이하에서는 모두 이러한 cpu 상승 현상이 있었던 것으로 기억합니다.
감사합니다.
