The GNOME team has started work for a new application, called GNOME Logs, which will be a centralized log viewer for systemd.
GNOME Logs enables the user to filter the detailed system event information and to search through it, in order to investigate the system problems.
GNOME Logs 0.1 has been released this morning, but it is unfinished and rough. It will be released as part of the GNOME 3.11.1 project, in a few weeks.
