Essential System Tools: QJournalctl – Graphical User Interface for systemd’s journalctl


journalctl is a command that’s used to identify many errors and for troubleshooting purposes. It’s an essential way of solving any issues with your Linux system.

Qjournalctl offers a handy graphical frontend for systemd’s journalctl command. It inevitably lacks some of the flexibility of journalctl, but it’s an eminently practical way of troubleshooting that can save some time.

Developer: Patrick Eigensatz with contributions by Simon Doppler

Qjournalctl is written in C++. Learn C++ with our recommended free books and free tutorials.

  1. I always appreciate in your reviews that you try out the software and display relevant screenshots which can be critical in deciding the usefulness of some software item.

    I would have thought that in the listing of all messages (and yes you pointed out that you can filter by log level) that critical messages should be in bright red, alerts in yellow etc in order to draw attention to them. And sometimes in tracking critical/alerts priority warnings it is useful to see the lower priority messages before them because they can be a clue as to why the serious incident occurred.
