Free Space Notifier

  • 772

On my Windows machines I use Task Scheduler to perform two tasks:

  • Inform me when the machine boots
  • Inform me if disk space is running low

I managed the first point in ubuntu using crontab.

In windows I manage the second point using Events. I setup task scheduler so that if event 2013 triggers I send an email.

It is possible to achieve the same with Ubuntu server?

Thanks

server

    Assuming you have some mail agent in the server (e.g. postfix)... try this

    #!/bin/bash
if [[ $(df --output=pcent / | grep -o '[0-9]*') -ge 80 ]]; then
  echo "You're running out of space" | mail picachu
fi

    df --output=pcent / returns the free space percentage of my root file system.

    grep strips the trailing % so if can compare integers.
