그래서 그냥 설치하기로..^^
문제는 mrtg는 기본이 root로 설정하고자 해서...
이번만 sudo를 사용하지 않고, 그냥 root 계정으로 설치한다.
| su -i |
입력하면 자주 보았던 # <- root 계정 접속.(비추천..^^)
내 설정은 현 리눅스가 아닌, 라우터의 정보를 받을 예정임.
귀차니즘으로 인하여 둘 다 설치.. 하지만 snmpd는 설정하지 않을 예정..
| apt-get install mrtg snmpd |
yes
기본 웹 디렉토리를 /var/www/mrtg
설정 파일은 /etc/mrtg.cfg
| mkdir /var/www/mrtg |
설정파일에 추가
| vi /etc/mrtg.cfg # Global Settings RunAsDaemon: yes EnableIPv6: no WorkDir: /var/www/mrtg Options[_]: bits,growright WriteExpires: Yes |
cron 파일 점검
| cat /etc/cron.d/mrtg |
cfg 파일 생성
| cfgmaker MRTG@192.168.1.1 > /etc/mrtg.cfg |
이미 ns-5gt에 snmp 설정을 하였다.
MRTG 이름으로 하였고, 사설 아이피인 기본 아이피로 사용중이다.
그리고 이 장비에서 서버 아이피로 snmp로 전송되게 설정이 끝난 상태이다.
아무런 메시지가 안 나오면 이상이 없는 것이다.
snmp 등 에러메시지가 나오면 점검해야한다.
HTML 파일을 생성한다.
| indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html |
그후 웹페이지로 확인한다.

이것은 mrtg가 root만 접속하기 때문에 이곳에 설정..
[While 님의 도음으로 수정합니다.]
나중에 cpu 및 ram도 테스트해야겠음..
여기까지만..

What is MRTG?
The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network links. MRTG generates HTML pages containing PNG images which provide a LIVE visual representation of this traffic.

Now we need to install mrtg and snmp
Installing MRTG in Debian
#apt-get install mrtg snmpd
The installation will create an mrtg subdirectory where the
Apache Web pages reside. On your Debian system the path of this
subdirectory is:
/var/www/mrtg
Now you need to edit the mrtg configuration file to edit the
some of the settings
File is located at /etc/mrtg.cfg
you need to change the global settings as follows
# Global Settings
RunAsDaemon: yes
EnableIPv6: no
WorkDir: /var/www/mrtg
Options[_]: bits,growright
WriteExpires: Yes
Title[^]: Traffic Analysis for
You will find a crontab running every 5 minutes as user root
# cat /etc/cron.d/mrtg
0-55/5 * * * * root if [ -x /usr/bin/mrtg ] && [ -r /etc/mrtg.cfg
]; then env LANG=C /usr/bin/mrtg /etc/mrtg.cfg >> /var/log/mrtg/mrtg.log
2>&1; fi
Now we need to assign the snmp community name in snmp
configration file /etc/snmp/snmpd.conf
# sec.name source community
# com2sec paranoid default public
com2sec readonly default public
#com2sec readwrite default private
Now you need to restart the snmp service
#/etc/init.d/snmpd restrat
The configuration file creating using
#cfgmaker public@localhost > /etc/mrtg.cfg
Creating a configuration file for a device using
#cfgmaker public@192.168.0.1 >> /etc/mrtg.cfg
With the configuration file created correctly there's only one
other thing you have to do and that's to use the indexmaker
utility to create the summary home page. Since you have to
re-run this command every time you make certain changes to the
/etc/mrtg.cfg configuration file,
Creating index file for the webserver using
#indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html
Now you need to reboot your system wait for five minutes or so
and then take a look at your summary home page. If your Debian
system's IP address is 172.16.0.20 then you'd type in the
following in the address bar of a browser running on a system on
the same network:
http://172.16.0.20/mrtg/
Your summary home page should come up with a graph for each
target entry in the configuration file. If a graph looks like
there's no data on it, click on it and check the statistics to
see if any traffic is being seen. Small amounts of traffic won't
show up on the graphs because we used the Unscaled statement
