Usage: systemd_failure_notify [CONFIG_FILE (absolute path)]
|
|
|
|
Notifies via mail when a service has failed. You need to place the following in the service which should be checked:
|
|
|
|
[Unit]
|
|
Description=...
|
|
OnFailure=systemd_failure_notify@%n.service
|
|
...
|
|
|
|
You should place the <scriptname>'s service into systemd's user and systemd's system folder so it can be used by global and user services.
|
|
|
|
If no CONFIG_FILE is given, HOME/.systemd_failure_notify.conf or /etc/systemd_failure_notify.conf is used. This fallback option
|
|
has to exist or the script will exit.
|
|
|
|
Configuration can be done in any file and any pre-defined variable can be overwritten.
|
|
|
|
The following are at least required for the script to work:
|
|
- SYSTEMD_FAILURE_NOTIFY_MAIL_ADDRESS="" // mail.rc has to be configured
|
|
|
|
You can copy this script to '/usr/local/bin' and use create a custom CONFIG_FILE as user. Examples can be found in '/usr/share/doc/<scriptname>'.
