除了修改配置文件外，还可以单独规划一个监控系统状态的配置文件，并使用crontab定时运行即可。

五、其他
以下是我增加的一些监控脚本：
1、Disk IO

引用

# cat diskperf.sh
#!/bin/bash
# This script will monitor the KBread/sec &KBwriten/sec of Disk.
# Creater: CCC IT loren ext:2288 2005/8/3
# As sda ,sdb,sdc,sdd,hda.

# disk=sda
hd=sda
disk=/dev/$hd
KBread_sec=`iostat -x $disk|grep $hd |awk '{print $8}'`
KBwrite_sec=`iostat -x $disk|grep $hd |awk '{print $9}'`
UPtime=`/usr/bin/uptime | awk '{print $3 " " $4 " " $5}'`
echo "$KBread_sec"
echo "$KBwrite_sec"
echo "$UPtime"
hostname

2、内存

引用

# cat mem.sh
#!/bin/bash
# This script to monitor 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"
hostname

3、SWAP

引用

# cat swap.sh
#!/bin/bash
# This script to monitor the swap usage.
totalswap=`/usr/bin/free |grep Swap |awk '{print $2}'`
usedswap=`/usr/bin/free |grep Swap |awk '{print $3}'`
UPtime=`/usr/bin/uptime | awk '{print $3 " " $4 " " $5}'`
echo "$totalswap"
echo "$usedswap"
echo "$UPtime"
hostname

4、磁盘

引用

# cat df.sh
#!/bin/bash
for etotal in `df -kl|grep -v 'Filesystem'|grep -v none|awk '{print $2}'`
do
let total=$total+$etotal
done
for eused in `df -kl|grep -v 'Filesystem'|grep -v none|awk '{print $3}'`
do
let used=$used+$eused
done
UPtime=`/usr/bin/uptime | awk '{print $3 " " $4 " " $5}'`
echo $total
echo $used
echo $UPtime
hostname

5、给予可执行权限

# chmod +x *

6、修改MRTG配置
