Essential System Tools: QJournalctl – Graphical User Interface for systemd’s journalctl
This is the latest in our series of articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For this article, we’ll look at QJournalctl, a Qt-based Graphical User Interface for systemd’s journalctl command. For details of all tools in this series, please check the table at the summary page of this article.
For many years system and kernel logs were handled by a utility called syslogd. Most Linux-based operating systems have since moved to systemd, which has a journal. It’s a giant log file for the whole system. Various software and services write their log entries into systemd’s journalctl. To view the output, there’s the command-line journalctl utility.
journalctl is a systemd utility. If your system doesn’t use systemd, you’ll have little interest in this utility. But given most popular Linux distros have adopted systemd, it’s likely you’ll need journalctl at one stage or another. It’s common sense to understand the system you’re running, and this utility will help you in this process.
