Scripts Required!

Postby refra » Thu Jan 07, 2010 12:36 pm

AOA,

I have a following file systems:

/dev/sda1 20G 8.1G 11G 43% /
/dev/sda3 40G 33G 5.3G 86% /d01
/dev/sdb 148G 113G 28G 81% /san
/dev/sdc 50G 84M 47G 1% /san01
/dev/sdd 403G 298G 85G 78% /san00

I need a script that if any file system exceed to 90% than email me.


Also if System load (w command) exceed to 5.00 then also mail me

Following script will send you an email once specified filesystems go over 90%



#!/bin/bash
output1=`df -lh | grep /dev/sda1 | awk '{print $5}' | sed 's/[!@#\$%^&*()]//g'`
output5=`df -lh | grep /dev/sda3 | awk '{print $5}' | sed 's/[!@#\$%^&*()]//g'`
output2=`df -lh | grep /dev/sdb | awk '{print $5}' | sed 's/[!@#\$%^&*()]//g'`
output3=`df -lh | grep /dev/sdc | awk '{print $5}' | sed 's/[!@#\$%^&*()]//g'`
output4=`df -lh | grep /dev/sdd | awk '{print $5}' | sed 's/[!@#\$%^&*()]//g'`
mail_address="your_mail_address"
function1(){
if [ $output1 -ge 90 ]
then
echo "filesystem Alert on "sda1"" | mail -s "filesystem alert" $mail_address
else
echo "nothing"
fi
}
function2(){
if [ $output2 -ge 90 ]
then
echo "filesystem Alert on sda3" | mail -s "filesystem alert" $mail_address
else
echo "nothing"
fi
}
function3() {
if [ $output3 -ge 90 ]
then
echo "filesystem Alert on sdc" | mail -s "filesystem alert" $mail_address
else
echo "nothing"
fi
}
function4() {
if [ $output4 -ge 90 ]
then
echo "filesystem Alert on sdd" | mail -s "filesystem alert" $mail_address
else
echo "nothing"
fi
}
function5() {
if [ $output5 -ge 90 ]
then
echo "filesystem Alert on sdb" | mail -s "filesystem alert" $mail_address
else
echo "nothing"
fi
}

following script will send you email once the system load goes over 5


output1=`uptime | awk '{print $11}' | cut -c 1`
mail_address="your_mail_address"
if [ $output1 -ge 5 ]
then
echo "System load is gone over 5" | mail -s "system load warning" $mail_address
else
echo "nothing"
fi

regarding scripts

Postby ghulam yaseen » Thu Jan 07, 2010 5:17 pm

but do remember, more the scripts you run...more the system memory and cpu usage will happen.....

Code: Select all

#!/bin/sh

IFS=
maybemail=`df | awk '$1 ~ /^\// {if ($5 > 90) {printf "%s is at %s\n", $6, $5}}';`
if [ -n "$maybemail" ]; then
  echo $maybemail | mail -s "file systems on `hostname` over 90%"
fi


Code: Select all

#!/bin/sh
if ! `awk '$1 > 5.00 { exit 1; }'  /proc/loadavg`; then
  cat /proc/loadavg | mail -s "load average on `hostname` is greater than 5.00"
fi


run them with cron.

Isn't it amazing how so many people can type "linuxpakistan.net" into their browsers but not "google.com"?
