Linux/Unix shell 脚本监控磁盘可用空间
Linux下监控磁盘的空闲空间的shell脚本,对于系统管理员或DBA来说,必不可少。下面是给出的一个监控磁盘空间空间shell脚本的样本,供大家参考。
1、监控磁盘的空闲空间shell脚本
[python] view plain copy print?
- robin@SZDB:~/dba_scripts/custom/bin> more ck_fs_space.sh
- #!/bin/bash
- # ------------------------------------------------------------------------------+
- # CHECK FILE SYSYTEM SPACE BY THRESHOLD |
- # Filename: ck_fs_space.sh |
- # Desc: |
- # The script use to check file system space by threshold |
- # Once usage of the disk beyond the threshold, a mail alert will be sent. |
- # Deploy it by crontab. e.g. per 15 min |
- # Usage: |
- # ./ck_fs_space.sh <percent> </filesystem [/filesystem2]> |
- # |
- # Author : Robinson |

- # ------------------------------------------------------------------------------+
- #
- # -------------------------------
- # Set environment here
- # ------------------------------
- if [ -f ~/.bash_profile ]; then
- . ~/.bash_profile
- fi
- export host=`hostname`
- export mail_dir=/users/robin/dba_scripts/sendEmail-v1.56
- export mail_list=‘Robinson.cheng@12306.com‘
- export mail_fm=‘oracle@szdb.com‘
- tmpfile=/tmp/ck_fs_space.txt
- alert=n
- # --------------------------------
- # Check the parameter
- # --------------------------------
- max=$1
- if [ ! ${2} ]; then
- echo "No filesystems specified."
- echo "Usage: ck_fs_space.sh 90 / /u01"
- exit 1
- fi
- # --------------------------------
- # Start to check the disk space
- # --------------------------------
- while [ "${2}" ]
- do
- percent=`df -P ${2} | tail -1 | awk ‘{print $5 }‘ | cut -d‘%‘ -f1`
- if [ "${percent}" -ge "${max}" ]; then
- alert=y
- break
- fi;
- shift
- done;
- # ------------------------------------------------------------------------
- # When a partition was above the threshold then send mail with df output
- # ------------------------------------------------------------------------
- if [ ! "${alert}" = ‘n‘ ];then
- df -h >$tmpfile
- mail_sub="Disk usage beyond the threshold ${max} on ${host}."
- $mail_dir/sendEmail -u ${mail_sub} -f $mail_fm -t $mail_list -o message-file=${tmpfile}
- fi;
- exit;
2、脚本说明
a、该脚本使用了 sendEmail 工具来发送邮件。
b、使用方式为"Usage: ck_fs_space.sh 90 / /u01" 。
c、脚本中使用了一个while循环来逐个判断所有的指定分区的空闲空间是否超出阙值。
d、对于超出阙值的情形发送邮件并且附上当前服务器上磁盘空间的使用情况。
