사용방법
~/rrdtool 디렉토리를 만들고 스크립트를 다운로드 받은 후 cron 에 1분마다 실행되도록 하면 설치는 완료된다.windy@wl ~/rrdtool $ crontab -l * * * * * /PATH/TO/rrd.sh windy@wl ~/rrdtool $ cat rrd.sh #!/bin/bash cd ~/rrdtool ./rrdtool_net.sh ./rrdtool_load.sh windy@wl ~/rrdtool $ ls -l -rwxr-xr-x 1 windy staff 222 7월 21일 14:16 rrd.sh* -rwxr-xr-x 1 windy staff 1018 7월 21일 13:54 rrdtool_load.sh* -rwxr-xr-x 1 windy staff 1950 7월 21일 14:14 rrdtool_net.sh* windy@wl ~/rrdtool $ ./rrd.sh windy@wl ~/rrdtool $ ls -l -rwxr-xr-x 1 windy staff 222 7월 21일 14:16 rrd.sh* -rw-r--r-- 1 windy staff 21458 7월 21일 14:25 rrdtool_load.png -rw-r--r-- 1 windy staff 93680 7월 21일 14:25 rrdtool_load.rrd -rwxr-xr-x 1 windy staff 1018 7월 21일 13:54 rrdtool_load.sh* -rwxr-xr-x 1 windy staff 1950 7월 21일 14:14 rrdtool_net.sh* -rw-r--r-- 1 windy staff 48760 7월 21일 14:25 rrdtool_net_e1000g0.rrd -rw-r--r-- 1 windy staff 22816 7월 21일 14:25 rrdtool_net_e1000g0_bit.png -rw-r--r-- 1 windy staff 23347 7월 21일 14:25 rrdtool_net_e1000g0_pks.png
로드 에버리지
시스템의 로드 에버리지를 얻어와 저장하고 그래프를 그린다. 솔라리스 기준으로, 리눅스나 다른 운영체제에서는 /tmp/rrdtool 를 확인해 [0.00:0.00:0.00]과 같이 제대로 가져오는지 확인해야 한다. 제대로 나오지 않으면 sed, awk 부분을 수정해야할 것이다.rrdtool_load.sh | 다운로드 |

네트워크 트래픽
시스템의 각 NIC마다 전송된 패킷 수 및 바이트 수를 얻어와 저장하고 그래프를 그린다. 솔라리스의 kstat 를 사용했다.rrdtool_net.sh | 다운로드 |
