UNIT - The name of the service unit.
LOAD - Information about whether the unit file has been loaded in the memory.
ACTIVE - The high-level unit file activation state, which can be active, reloading, inactive, failed, activating, deactivating. It is a generalization of the SUB column.
SUB - The low-level unit file activation state. The value of this field depends on the unit type. For example, a unit of type service can be in one of the following states, dead, exited, failed, inactive, or running.
DESCRIPTION - Short description of the unit file.

$ systemctl list-units
UNIT                  LOAD   ACTIVE SUB       DESCRIPTION
crond.service         loaded active running   Command Scheduler
ntpd.service          loaded active running   Network Time Service
zabbix-agent.service  loaded active running   Zabbix Agent
...

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

136 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
