一步一步安裝服務器監視軟件MRTG

MRTG(MultiRouter Traffic Grapher, MRTG)是基於SNMP的典型網絡流量統計分析工具。它耗用的系統資源很小，所以有不少外掛的程序也依附在MRTG下。它經過SNMP協議從設備獲得其流量信息，並將流量負載以包含PNG格式圖形的HTML文檔的方式顯示給用戶，以很是直觀的形式顯示流量負載。

 

1、安裝網絡流量監視

首先確認系統中已經安裝如下套件：
gd、gd-devel、libpng、libpng-devel、libpng十、libpng10-devel、zlib、zlib-devel、perl、gcc、apache、net-snmp

編輯snmpd.conf
vi /etc/snmp/snmpd.conf
#view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc //去掉註釋
access notConfigGroup "" any noauth exact systemview none none //systemview改成mib2

啓動apache、snmp服務
/usr/local/apache2/bin/apachectl start
/etc/init.d/snmpd start

安裝mrtg
#tar zvxf mrtg-2.14.5.tar.gz
#cd mrtg-2.14.5
#./configure --prefix=/usr/local/mrtg
#make
#make install

配置mrtg
#mkdir /usr/local/apache2/htdocs/mrtg
#cd mrtg-2.14.5
#cp ./p_w_picpaths/* /usr/local/apache2/htdocs/mrtg/p_w_picpaths/
#/usr/local/mrtg/bin/cfgmaker public@127.0.0.1 --global "workdir: /usr/local/apache2/htdocs/mrtg" --output=/usr/local/apache2/htdocs/mrtg/mrtg.cfg
#/usr/local/mrtg/bin/indexmaker --output=/usr/local/apache2/htdocs/mrtg/index.html --title="MRTG on Linux" /usr/local/apache2/htdocs/mrtg/mrtg.cfg

運行mrtg
#env LANG=C /usr/local/mrtg/bin/mrtg /usr/local/apache2/htdocs/mrtg/mrtg.cfg

設置crontab(每五分鐘運行一次)
#crontab -e
*/5 * * * * env LANG=C /usr/local/mrtg/bin/mrtg /usr/local/apache2/htdocs/mrtg/mrtg.cfg

2、安裝CPU負載監視

首先安裝sysstat套件

創建CPU腳本：
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

使腳本能夠執行：
chmod +755 /opt/mrtg/mrtg.cpu

修改/usr/local/apache2/htdocs/mrtg/mrtg.cfg在文件最後加入cpu項目
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]: <H1>CPU Loading</H1>

3、安裝WWW鏈接數監視

創建WWW腳本：
mkdir /opt/mrtg
vim /opt/mrtg/mrtg.www

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

使腳本能夠執行：
chmod +755 /opt/mrtg/mrtg.www

修改/usr/local/apache2/htdocs/mrtg/mrtg.cfg在文件最後加入www項目
Target[www]: `/opt/mrtg/mrtg.www`

usedmem=`/usr/bin/free |grep Mem |awk '{print $3}'`
UPtime=`/usr/bin/uptime | awk '{print $3""$4""$5}'`
echo $totalmem
echo $usedmem
echo $UPtime
hostname

使腳本能夠執行：
chmod +755 /opt/mrtg/mrtg.ram

修改/usr/local/apache2/htdocs/mrtg/mrtg.cfg在文件最後加入ram項目
Target[ram]: `/opt/mrtg/mrtg.ram`
#Unscaled[ram]: dwym
MaxBytes[ram]: 2048000
Title[ram]:Memory
