Debian/Ubuntu Linux에서 Munin을 이용하여 서버와 클라이언트를 나눠 모니터링 하는 방법에 대해 알아 보겠습니다.
(tested : Debian Squeeze)

– Server 설정

* munin 설치

[email protected]:~# apt-get install -y munin munin-node

 

* munin.conf 설정
사용자 환경에 맞도록 설정 합니다.

[email protected]:~# nano /etc/munin/munin.conf
dbdir /var/lib/munin
htmldir /var/cache/munin/www
logdir /var/log/munin
rundir /var/run/munin
includedir /etc/munin/munin-conf.d

[yongbok;www]
address 127.0.0.1
use_node_name yes

[yongbok;mirror]
address 192.168.0.2
use_node_name yes

 

* munin-node.conf 설정

[email protected]:~# nano /etc/munin/munin-node.conf
host_name yongbok.net
allow ^127\.0\.0\.1$
allow ^192\.168\.0.\2$

 

– Client 설정

[email protected]:~# apt-get install -y munin-node
[email protected]:~# nano /etc/munin/munin-node.conf
host_name mirror.yongbok.net
allow ^127\.0\.0\.1$
allow ^192\.168\.0\.1$

 

– 공통
munin-node를 실행합니다.

[email protected]:~# /etc/init.d/munin-node start
Starting Munin-Node: done.

 

이제 매 5분마다 그래프가 그려집니다.
정상적으로 데이터를 읽어오는지 확인 합니다.

 

* Server logs
