Install a cron job to periodically monitor disk use, and send a notification email if space exceeds the configured threshold

ansible-role-simple-disk-space-notify

Install a cron job to periodically monitor disk use, and send a notification email if space exceeds the configured threshold

This is a trivial script for simple/legacy servers. You can use it as a backup, but you should have better monitoring in place.

See defaults/main.yml for config options.

Requirements

• The mail command line util must be installed.
• You must have already configured your server to be able to deliver mail to the outside world.

The acromedia.postfix is a good starting place for the above.

List inodes of /boot/efi produces warning

Cron emits the following error daily on 22.04 servers:

WARN: Cannot evaluate inode table use for '/boot/efi'; Expected PERCENT_USE to be a positive integer. Got '-' instead.

Output of df shows a dash instead of a percetage, and the mount appears to use zero inodes:
