journal-notify
==============
**Notify about journal log entries**
This runs in 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](https://developer.gnome.org/notification-spec/)
* [libsystemd](https://www.github.com/systemd/systemd)
* [markdown](https://daringfireball.net/projects/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 expexted 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!
