The state mapping is configurable, by default active and inactive states are OK, failed and all others are CRIT.

The socket unit name.

Discovery

By default, no sockets are discovered. For a socket to be discovered it has to match the conditions in the ruleset "Systemd single socket discovery". Moreover, only systemd units listed by 'systemctl --all' are considered. It is not sufficient for the socket to be listed by 'systemctl list-unit-files'. Note, that even if a systemd unit is 'loaded', this does not mean it will be listed by 'systemctl --all'.
