systemctl

Returns a list of the units, whether they are loaded, active, their sub and description.

systemctl is-failed

Returns a list of status only.

What is the syntax to return the details of the failed units?

You can use systemctl list-units --state=failed to list all failed units.

The parameters for systemctl are documented in the man page systemctl(1).

    --failed is an alias for --state=failed

    Yes thats right, but until 2017-02-02 --failed wasn't documented and marked as deprecated in the codebase (#5198)

    I see. And from the PR discussion I learned that we can drop list-units and go with systemctl --failed by itself :)

    I find it very irritating that systemctl status tells me the one+ things are failed, but wont tell me what. I need to run another command, not under the status subcommand to find out. Shame. Jun 22 '18 at 3:02
  • @NathanLilienthal request a change from the systemd folks. They are quite opinionated on "the one right way of doing things", though.

This is more simple:

systemctl --failed
