systemd-utils

Random systemd utilities and unit files.

Usage

Recommended location:

cd $HOME/.config/systemd
git clone https://github.com/kylemanna/systemd-utils.git utils

Symlink or hardlink unit files into $HOME/.config/systemd/user. Systemd appears to have some issues with symlinked unit files at the time of writing.

Scripts

On Failure

Allows users to specify OnFailure=failure-email@%i.service under [Unit] section of systemd files.
The failure-email service will email the user when a service fails unexpectedly and include the systemd status <svc> output.

Example configuration systemd file:

  [Unit]
  ...
  OnFailure=failure-email@%i.service

Failure Monitor

Systemd service that runs and parses the output of journalctl. When a task fails, an email is sent to the user at the configured email address.
The failure-monitor service will email the user when a service fails unexpectedly and include the systemd status <svc> output.

Example configuration:

  $ systemctl --user start failure-monitor@test@gmail.com.service

Email Journal Log

Upon completion of a script (i.e. a daily backup script), send an email of the log output. The following code should be used to save a cursor before the execution of the service and send all the data followign that cursor.

ExecStartPre=/bin/sh -c 'journalctl -o cat -n 0 -u %n --show-cursor | cut -f3 -d" " > /run/%n.cursor'

ExecStart=...

ExecStopPost=/bin/sh -c '/etc/systemd/scripts/systemd-email you@example.com %n $(cat /run/%n.cursor)'
ExecStopPost=/bin/rm -f /run/%n.cursor

It would be nice if systemd provided a reference to a cursor prior to the most recent invocation of the service (like the --boot option refers to this boot). Until then hack around it.
