Check Container's state

item B<--port>
Port used by Docker

Specify one container's id
=item B<--name>
Specify one container's name
=head2 MODE OPTIONS
=item B<--threshold-overload>
Set to overload default threshold values (syntax: section,status,regexp)
It used before default thresholds (order stays).
Example: --threshold-overload='state,CRITICAL,^(?!(Paused)$)'
