=item B<--filter-counters>

Only display some counters (regexp can be used).
Example: --filter-counters='status'

=item B<--warning-status>

Set warning threshold for status (Default: '').
Can used special variables like: %{status}, %{display}

=item B<--critical-status>

Set critical threshold for status (Default: '%{status} !~ /^registered/').
Can used special variables like: %{status}, %{display}

=item B<--warning-*> B<--critical-*>

Thresholds.
Can be: 'total-registered', 'total-unregistered', 'total-rejected', 
'total-unknown', 'total-partiallyregistered'.
