This article will explain in detail the Shell script on how to monitor disk usage. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Monitordisk.sh is as follows

The code is as follows:

#! / bin/bash

# Updated:2008-03-03 PM By:leif (liangliwen@163.com)

EMAIL=/usr/local/bin/email

/ bin/df-h > / tmp/df.txt

USE= `df-H | grep-o [0-9] *% | grep-o'[0-9]\ +'`

For i in $USE

Do

If (($I > 95))

Then

$EAMIL-s "WARNING Low disk space for $I" liangliwen@163.com break

Fi

If (($I > 90))

Then

$EMAIL-s "Low disk space for $I" liangliwen@163.com fi

Done

/ bin/rm-f / tmp/df.txt

To achieve the goal, any partition will send an email to the designated recipient when it reaches 90%, and a warning (warning) will be issued on the subject of the email at 95%, indicating that the email program EMAIL is downloaded and installed from http://www.cleancode.org/projects/email, which is more flexible.

Put this shell in the crontab implementation to check the disk condition regularly as needed.

The following is a supplementary content:

Shell script to monitor remote host disk usage, filename: disklog.sh

The code is as follows:

#! / bin/bash

# File name: disklog.sh

# purpose: monitor disk usage of remote systems

Logfile= "diskusage.log"

If [[- n $1]]

Then

Logfile=$1

If

If [!-e $logfile]

Then

Printf "%-8s%-14s%-9s%-8s%-6s%-6s%-6s%\ n" Date "," IP ADDRESS "," Device "," Capacity "," Used "," Free "," Percent "," Status "> $logfile

Fi

IP_LIST= "127.0.0.1 0.0.0.0"

# provide remote host IP address list

(

For ip in $IP_LIST

Do

Ssh slynux@$ip'df-H' | grep ^ / dev/ > / tmp/$$.df

While read line

Do

Cur_date=$ (date +% D)

Printf "%-8s%-14s" $cur_date $ip

Echo $line | awk'{printf ("%-9s%-8s%-6s%-6s%-8s", $1mine2);}'

Pusg=$ (echo $line | egrep-o "[0-9] +%")

Pusg=$ {pusg/\% /}

If [$pusg-lt 80]

Then

Echo SAFT

Else

Echo ALERT

Fi

Done

> $logfile

We can use cron to schedule script execution at regular intervals, such as adding an entry like this to crontab to run the script automatically at 10:00 every morning:

00 10 * / home/sh/disklog.sh / home/log/diskusg.log

Execute the crontab-e command, add the above line, and save it.

You can also perform it manually:

$. / disklog.sh
