Build Status

seat-inspect

seat-inspect is a command line tool for producing status reports of systemd facilities such as Multi-Seat, Inhibitor Locks, Services, Targets, and other types of Unit.

The intent of running the code is to have an overview of the system status, both to see what the new facilities are about, and to figure out if there is something out of place.

The intent of reading the code is to have an idea of how to use these facilities: the code has been written to be straightforward and is annotated with relevant bits from the logind and systemd D-Bus API documentation.

See also here for general definitions, and the Documentation for Developers section over here for more detailed information.

EXAMPLE OUTPUT

sudo seat-inspect

NOTES

seat-inspect is not a finished tool, but a starting point. Enrico Zini put the first verison on github hoping that people would fork it and add their own extra sanity checks and warnings, that it could grow not only into a standard thing to run if a system acts weird, but also a standard thing to hack on for those trying to learn more about Multi-Seat and systemd.

As it is now, it should be able to issue warnings if some bits are missing for network-manager or shutdown functions to work correctly, or if some Devices or Services are having problems. It all needs more testing by people with systems that are experiencing such issues.

Tinkering with the code can be an interesting way to explore the new functionalities that we recently grew. Ofcourse, the same can be done, and in more detail, with loginctl, systemctl, and journalctl calls of various configuration, but seat-inspect provides the only high-level view of everything.
