Sadly there are lots of basic must-have tasks that Linux distros simply do not support out of the box. It's not so much an OS as a kit for making operating systems. Backup is another. Here's how I set up email monitoring of systemd services, for anyone who wants it: https://gist.github.com/mikehearn/f1db694f24eaa05c753e5a7598... It consists of three parts. Firstly a shell script that will email the unit status colorized to your preferred email address. Secondly, a service file that tells systemd how to call it, and finally, an OnFailure line in each service that you want to monitor. You can use systemd's support for overlays to add this to existing services you didn't write yourself. You also have to make sure that your server can actually send mail to you. Installing default-mta will get you an SMTP relay that's secure out of the box but your email service will consider it spam. If you use gmail it's typically sufficient to just create a filter that ensures emails from your server are never marked as spam. |
