journal-notify
Notify about journal log entries
This runs in the background and produces notifications whenever systemd journal logs an entry. Notifications look like this:
Before flooding the desktop this will throttle notifications:

Requirements
To compile and run journal-notify you need:
- libnotify ↗️
- libsystemd ↗️
- markdown ↗️ (HTML documentation)
gnome-icon-theme(or whatever includes the icons you want to use)
To use journal-notify you probably want systemd-journald.
Some systems may require additional development packages for the libraries.
Look for libnotify-devel, libsystemd-devel or similar.
Build and install
Building and installing is very easy. Just run:
make
followed by:
make install
This will place an executable at /usr/bin/journal-notify,
documentation can be found in /usr/share/doc/journal-notify/.
Usage
To use journal-notify you need access to the journal log files. Make sure
you get the expected log entries by running journalctl. Possibly you have
to add yourself to group systemd-journal or similar.
Just running journal-notify without parameter will show all log entries.
Be warned: This can flood your disktop with notifications.
journal-notify accepts some options:
- -a: combine matches with a logical AND
- -e: use extended regular expressions
- -h: show help
- -i ICON: icon to use
- -m MATCH: This can be specified more than once. The option accepts matches
to systemd journal fields. (see
man 7 systemd.journal-fields) - -n: no case sensitive regular expressions
- -o: combine matches with a logical OR
- -r REGEX: This add a regular expression match for the message field.
- -t SECONDS: seconds to show the notification, 0 is forever
- -T THROTTLE: start throttling with Nth notification
- -v: verbose output, can be specified multiple times
- -V: print version information
- -x EXECUTABLE: execute EXECUTABLE
- -X EXECUTABLE: execute EXECUTABLE, do not show notification
The screenshot shown above resulted from this command:
journal-notify -m SYSLOG_IDENTIFIER=sshd -e -r "^(error:|Accepted)" -i security-high
The command specified by -x is called with three options. Make sure
your executable understands these options:
- -i: syslog identifier
- -p: priority
- -m: message
Additionally example desktop files are installed to
/usr/share/journal-notify/desktop/. You should copy them to
~/.config/autostart/ to enable autostart or create your own desktop files
there.
Example execute scripts are installed to /usr/share/journal-notify/execute/.
Review and update them before execution, for example you should replace the
mail address in mail.sh with your own one.
Example systemd units are installed to /usr/share/journal-notify/systemd/.
To use them copy to /etc/systemd/system/ and systemctl enable. Again, make
sure to change unit file and script for your needs!
