###################mrtg.cpu################################
[root@localhost mrtgsh]# vi /usr/local/apache2/htdocs/mrtgsh/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

 

chmod 755 /usr/local/apache2/htdocs/mrtgsh/mrtg.cpu

####################端口脚本##############################

建立8030脚本：

vi /usr/local/apache2/htdocs/mrtgsh/mrtg.8030

#!/bin/bash
all=`netstat -a | grep 8030|awk '{print $5}'|sort | wc -l|awk '{print$1 - 1}'`
user=`netstat -a | grep 8030|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 /usr/local/apache2/htdocs/mrtgsh/mrtg.8030

 

修改 /etc/mrtg/mrtg.cfg 在文件最后加入8030项目
Target[8030]: `/usr/local/apache2/htdocs/mrtgsh/mrtg.8030`
MaxBytes[8030]: 500
Title[8030]: 8030 Connect
Options[8030]: nopercent, growright, gauge
YLegend[8030]: Online Users
ShortLegend[8030]: &

LegendO[8030]:   Online :
PageTop[8030]:

######################内存监视######################
vi /usr/local/apache/htdocs/mrtgsh/mrtg.memory
添加如下脚本：
#!/bin/bash 
# run this script to check the mem usage. 
totalmem=`/usr/bin/free |grep Mem |awk '{print $2}'` 
usedmem=`/usr/bin/free |grep Mem |awk '{print $3}'` 
UPtime=`/usr/bin/uptime | awk '{print $3""$4""$5}'` 
echo $totalmem 
echo $usedmem 
echo $UPtime 
让其具有运行权限
chmod 755 /usr/local/apache2/htdocs/mrtgsh/mrtg.memory
 
3.编辑/etc/mrtg/mrtg.cfg
添加如下内容
Target[memory]: `/usr/local/apache2/htdocs/mrtgsh/mrtg.memory` 
MaxBytes[memory]: 4096000 
Title[memory]:Memory Usages
ShortLegend[memory]: & 
kmg[memory]:kB,MB 
kilo[memory]:1024 
YLegend[memory]:   Memory Usage : 
Legend1[memory]:   Total Memory : 
Legend2[memory]:   Used Memory : 
LegendI[memory]:   Total Memory : 
LegendO[memory]:   Used Memory : 
Options[memory]: growright,gauge,nopercent
