Script To Monitor disk Usage


Hello All,

Many times we have a requirement to automate few of the tasks, and one of the important task is to delete old log files from log destination.

We usually get the conditions where we have to delete the log from particular directory when it reaches to some thresh hold value.

Now a day the requirement of automation is highly increased where we are seeing most of the day to day tasks are getting automated using different scripting languages.

Its always a good idea to automate your daily tasks which will save your working hours and will increase your productivity.

Most of the time log destination gets full and due to which we face other issues like application down or particular service stop working.

And manual deleting of log is hectic process so below script will help you to delete your log data when it meets your condition, and also it will trigger mail to recipient after deletion of logs.

You can schedule this script in your crontab according to your feasible time to run it.

Below script will help you in getting disk usage alert. it will also delete the particular directory log on given condition.

Capacity=`df -P /var/log/audit/ | awk '{ gsub("%",""); capacity = $5 }; END { print capacity }'`

echo "capacity:" $Capacity


if [ $Capacity -gt 3 ]

then

rm -rf /var/log/audit/audit.log.*
