2.檢測內存

#!/bin/bash#Inspect Memory : If the memory is less than 500 , then send mail to wl#Tue Aug 2 09:13:43 CST 2016 PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/wl/bin export PATH MEM=$(free -m | grep "Mem" | awk '{print $4}') if [[ MEM < 500 ]];then echo -e "Memory Warning : Memory free $MEM" > /service/script/.MemoryWarning mail -s "Memory Warning" wl < /service/script/.MemoryWarning fi

3.檢測磁盤剩余空間

4.檢測剩余Inode

#!/bin/bash#Inspcet Inode : If the free INODE is less than 200, the message is sent to the wl#Tue Aug 2 10:21:29 CST 2016 PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/wl/bin export PATH for FreeInode in $(df -i | grep -v "Filesystem" | awk '{print $4}') do if [[ $FreeInode < 200 ]];then echo -e "$(df -i | grep "$FreeInode")" > /service/script/.FreeInode mail -s "FreeInode Warning" wl < /service/script/.FreeInode fi done
