You'll need Linux, bash, and a working sendmail, msmtp or mail command. Your RAM is assumed.

git clone https://github.com/IainKay/ram-altman.git
cd ram-altman
chmod +x ram-altman.sh test-ram-altman.sh

./ram-altman.sh --status    # see the evidence against you
./ram-altman.sh --dry-run   # preview an email without sending it

Example output, from a simulated machine that has confessed to everything:

Total:      15.3 GiB
Used:       6.7 GiB
Available:  8.6 GiB (56.2%)
  Free:     0.3 GiB
  Cache:    8.2 GiB

To run it for real, add this to your crontab with crontab -e:

RAM_ALTMAN_TO=recipient@example.com
RAM_ALTMAN_FROM=you@example.com
RAM_ALTMAN_FROM_NAME=Your Name

*/5 * * * * /path/to/ram-altman.sh

It samples every five minutes and emails at most once a day. If a send fails, it tries again on the next run, because this message matters.
