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.
Nov 22 11:04:36 mysystem systemd: Triggering OnFailure= dependencies of crond.service.
Nov 22 11:04:36 mysystem systemd: crond.service failed.
Nov 22 11:04:41 mysystem systemd: crond.service holdoff time over, scheduling restart.
Nov 22 11:04:41 mysystem systemd: Stopped Command Scheduler.
Nov 22 11:04:41 mysystem systemd: Started Command Scheduler.
Nov 22 11:04:41 mysystem systemd: Starting crond failure email notification...
Nov 22 11:04:41 mysystem systemd: Started crond failure email notification.
... 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 ...
