给Ubuntu服务器安装MRTG监控软件:

一:安装网络流量监视[默认5分钟采集一次]

切换到超级用户:
sudo -sH

安装软件:
apt-get install apache2
apt-get install mrtg
apt-get install snmpd

编辑snmpd:
vim /etc/snmp/snmpd.conf

查找到类似的行,修改为如下所示:(仅仅修改屏蔽或放开)
# sec.name source community
# com2sec paranoid default public # kommentieren
com2sec readonly default public # <- auskommentieren
#com2sec readwrite default private

重启snmpd服务:
/etc/init.d/snmpd restart

重新生成mrtg的配置文件:
cfgmaker public@localhost > /etc/mrtg.cfg

(注意)如果仅仅监视一个IP地址采用如下命令:
cfgmaker public@192.168.0.1 >> /etc/mrtg.cfg

生成mrtg的主页:
indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html

访问:
http://localhost/mrtg/

二安装CPU负载监视[默认5分钟采集一次]

切换到超级用户:
sudo -sH

安装软件:
apt-get install sysstat

建立CPU脚本:
mkdir /opt/mrtg
vim /opt/mrtg/mrtg.cpu
#!/bin/bash
cpuusr=`/usr/bin/sar -u 1 3 | grep Average | awk '{print $3}'`
cpusys=`/usr/bin/sar -u 1 3 | grep Average | awk '{print $5}'`
UPtime=`/usr/bin/uptime | awk '{print $3""$4""$5}'`
echo $cpuusr
echo $cpusys
echo $UPtime
hostname

使脚本可以执行:
chmod +755 /opt/mrtg/mrtg.cpu

修改 /etc/mrtg.cfg 在文件最后加入cpu项目
Target[cpu]: `/opt/mrtg/mrtg.cpu`
MaxBytes[cpu]: 100
Options[cpu]: gauge, nopercent, growright
YLegend[cpu]: CPU loading (%)
ShortLegend[cpu]: %
LegendO[cpu]:   CPU us;
LegendI[cpu]:   CPU sy;
Title[cpu]: CPU Loading
PageTop[cpu]:

CPU Loading



重新生成索引页面:
indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html

三安装WWW连接数监视[默认5分钟采集一次]

切换到超级用户:
sudo -sH

建立WWW脚本:
mkdir /opt/mrtg
vim /opt/mrtg/mrtg.www
#!/bin/bash
all=`netstat -a | grep www|awk '{print $5}'|sort | wc -l|awk '{print$1 - 1}'`
user=`netstat -a | grep www|awk '{print $5}'|cut -d":" -f1|sort| uniq |wc -l | awk '{print $1 - 1}'`
if [ "$all" = "-1" ]; then
echo 0
else
echo $all
fi
if [ "$user" = "-1" ]; then
echo 0
else
echo $user
fi
UPtime=`/usr/bin/uptime | awk '{print $3 " " $4 " " $5}'`
echo $UPtime
hostname


使脚本可以执行:
chmod +755 /opt/mrtg/mrtg.www

修改 /etc/mrtg.cfg 在文件最后加入www项目
Target[www]: `/opt/mrtg/mrtg.www`
MaxBytes[www]: 500
Options[www]: nopercent, growright
YLegend[www]: Online Users
ShortLegend[www]: %
LegendI[www]:   Connect :
LegendO[www]:   Online :
Title[www]: WWW Connect
PageTop[www]:

WWW Connect



重新生成索引页面:
indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html
