Hellos,
Yes, I did some tests with "OnFailure" attribute, but the result was the same: system didn't sent any mail. Daemon and script files were:
- crond.service:
- [Unit]
Description=Command Scheduler After=auditd.service systemd-user-sessions.service time-sync.target OnFailure=crond-notify-email.service [Service] EnvironmentFile=/etc/sysconfig/crond ExecStart=/usr/sbin/crond -n $CRONDARGS ExecReload=/bin/kill -HUP $MAINPID KillMode=process Restart=on-failure RestartSec=5s [Install] WantedBy=multi-user.target
- crond-notify-email.service:
- [Unit]
Description=crond failure email notification After=crond.service Requires=crond.service [Service] Type=oneshot ExecStart=/etc/systemd/system/mail-notification.sh
- /etc/systemd/system/mail-notification.sh
- #!/bin/bash
echo "Crond restarted" | /usr/bin/mailx -s "Crond failure notification" myemail@mydomain
After "systemctl daemon-reload" and "kill -9 `pidof crond`", message log are: Nov 22 11:04:36 mysystem systemd: crond.service: main process exited, code=killed, status=9/KILL Nov 22 11:04:36 mysystem systemd: Unit crond.service entered failed state.

... but I don't receive any email...
Why?
Works for me - but I have the extras for crond.service (or any other service) as:
[Unit] OnFailure=unit-status-mail@%n.service
[Service] Restart=on-failure RestartSec=5s
and unit-status-mail@.service contains something like:
[Unit] Description=Unit Status Mailer Service After=network.target
[Service] Type=simple ExecStart=/path/to/mailer/script
I got this info a while ago from http://northernlightlabs.se/systemd.status.mail.on.unit.failure - but that no longer exists ...
