check mk 의 설치는 끝났고 이제부터가진짜시작이다.
아주 다양한 방법으로 모니터링이 가능한데 check-mk 에서 제공 해주는 plugin 말고도 nagios 에서 제공되는 스크립트도 있으니 이것도 찾아보면 좋을 것 같다.
오늘은 check mk에서 제공하는 plugin 으로 기본적인 모니터링 요소 추가까지 함.
login 후 오른쪽에 ‘hosts’ 텝을 클릭하고 ‘New folder’ 메뉴로 들어간다.
testfolder2 라는 폴더를 만들었다. 이제 여기에 host2를 추가해 넣을거다.
‘New host’ 메뉴에서 host를 추가한다.
이 름은 host2로 추가함. 이 host2 가 check_mk가 서비스 되고 있는 서버의 hosts 파일에 등록이 되어 있던지 dns에 등록이 되어 있어야함. 정보를 받을 agent type은 check_mk agent와 snmp 둘 다 쓰기로 설정 함.
criticality는 비지니스 critical 로 설정했다.
그리고 save & test 메뉴를 클릭한다.
test를 해보면 ping test는 성공 하는데, agent와 snmp test가 실패로 나온다.
이제 agent 와 snmp 설정을 해주자.
management agents 메뉴에서 check-mk-agent rpm 을 host2 에 다운받는다.

다시 돌아가서 test 를 해보자.
agent 와 snmp 서비스 정보 둘다 잘 받아오는것을 볼 수 있다.
WATO configuration 에 hosts 메뉴를 눌러서 Mail director 메뉴를 보면 ‘!’ 표시가 되어있고 ‘6 Changes’ 가 되어있다. 클릭해서 변경 확인을 해주자.
‘Activate Changes!’ 를 눌러서 바뀐 항목들을 실행 시켜주자.
Overview 에서 ‘All hosts’ 메뉴에서 host2를 들어간다.
등록된 감시 목록이 없어서 별거 안보인다. ‘WATO’ 메뉴에 들어간다.
services 에 들어간다.
‘Full Scan’ 을 클릭하고 ‘Activate missing’을 클릭하면 발견된 감시 목록들을 전부 등록한다.
다시 변경사항을 적용 시켜준다.
다시 host2 의 감시 서비스 항목을 살펴 보면 몇개가 펜딩 되어 있을 텐데 아래 사진의 리사이클 버튼을 눌러주면 다시 정보들을 가져온다.
서비스에 따라 좀 늦게 가져 오는것도 있다.
이상 check_mk 의 기본 서비스들 등록 하는방법이엇다.
