Hey Paul,
Check out OnFailure=
[Unit]
Description="HTTP Service"
OnFailure=mail-root@http.service
...
The mail-root@.service is a generic oneshot service that mails you
some stuff.
[Unit]
Description="Mailer"
[Service]
Type=oneshot
ExecStart=/path/to/my/mail-script %i
[Install]
WantedBy=multi-user.target
And your mail-script is somthing like...
#!/usr/bin/env sh
systemctl status "${1}.service" | \
mail -s "Failed Service: ${1}" admin@xxxxxxxxxxx
See:
