请问监控Linux服务器磁盘容量的脚本怎么写？

看看下面这个脚本（注意要用英文的标点符号）：

#!/bin/bash

partion_list=( 'df -h | awk ‘NF>3&&NR>1{sub(/%/,””,$(NF-1))print $NF,$(NF-1)}’' )

critical=90

notification_email()

{

emailuser='user@qq.com' “发送邮件地址”

emailpasswd='password'“成功开启POP3/SMTP服务,在第三方客户端登录时，密码框请输入的授权码”

emailsmtp='smtp.qq.com'

sendto='user2@qq.com' “接收邮箱地址”

title='Disk Space Alarm' “邮件标题”

/usr/local/bin/sendEmail -f $emailuser -t $sendto -s $emailsmtp -u $title -xu $emailuser -xp $emailpasswd -m $emailmessage

}

crit_info=””

for (( i=0i<${#partition_list[@]}i+=2 ))

do

if [ “${partition_list[ ((i+1)) ]}” -lt “$critical” ]then

echo “ok! ${partition_list[i]} used ${partition_list[ ((i+1)) ]}%”

else

if [ “${partition_list[ ((i+1)) ]}” -gt “$critical” ]then

crit_info=$crit_info”Warning!!! ${partition_list[i]}

used ${partition_list[ ((i+1) ] }%\n”

fi

fi

done

if [ “$crit_info” != ”” ]then

echo -e $crit_info | notification_email

fi

上面脚本的功能是监控每个磁盘分区，当磁盘分区使用空间超过90%时，就通过sendEmail来发送邮件告警。sendEmail是个开源工具，可以从http://caspian.dotconf.net/menu/Software/SendEmail/sendEmail-v1.56.tar.gz下载；

解压后把sendEmail拷贝到/usr/local/bin下即可。

1、查看物理CPU数

[root@MysqlCluster01 ~]# cat /proc/cpuinfo |grep "physical id"|sort |uniq|wc -l

1

2、查看逻辑CPU数

[root@MysqlCluster01 ~]# cat /proc/cpuinfo |grep "processor"|wc -l

4

3、查看CPU几核（即核数）

[root@MysqlCluster01 ~]# cat /proc/cpuinfo |grep "cores"|uniq

cpu cores : 4

4、查看CPU主频

[root@MysqlCluster01 ~]# cat /proc/cpuinfo |grep MHz|uniq

cpu MHz : 2499.982

5、前 *** 作系统内核信息

[root@MysqlCluster01 ~]# uname -a

Linux MysqlCluster01 2.6.32-431.20.3.el6.x86_64 #1 SMP Thu Jun 19 21:14:45 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

6、前 *** 作系统发行版信息

[root@MysqlCluster01 ~]# cat /etc/issue

CentOS release 6.4 (Final)

Kernel \r on an \m

7、内存使用情况

[root@MysqlCluster01 ~]# free -m

total used free shared buffers cached

Mem: 7863 2738 5125 0 141 835
