Linux常用的服务器监控shell脚本(2)

 
 

 

3、监控主机的磁盘空间,当使用空间超过90％就通过发mail来发警告

 
#!/bin/bash

#monitor available disk space

SPACE='df | sed -n '/ \ / $ / p' | gawk '{print $5}' | sed  's/%//'

if [ $SPACE -ge 90 ]

then

[email protected]

fi

 

4、 监控CPU和内存的使用情况

 
#!/bin/bash

#script  to capture system statistics

OUTFILE=/home/xu/capstats.csv

DATE='date +%m/%d/%Y'

TIME='date +%k:%m:%s'

TIMEOUT='uptime'

VMOUT='vmstat 1 2'

 USERS='echo $TIMEOUT | gawk '{print $4}' '

LOAD='echo $TIMEOUT | gawk '{print $9}' | sed "s/,//' '

FREE='echo $VMOUT | sed -n '/[0-9]/p' | sed -n '2p' | gawk '{print $4} ' '

IDLE='echo  $VMOUT | sed -n '/[0-9]/p' | sed -n '2p' |gawk '{print $15}' '

echo "$DATE,$TIME,$USERS,$LOAD,$FREE,$IDLE" >> $OUTFILE

 

 

5、全方位监控主机

 #!/bin/bash
# check_xu.sh

# 0 * * * * /home/check_xu.sh
