=item B<--filter-name>

Filter name (can be a regexp).

=item B<--filter-counters>

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

=item B<--warning-*>

Threshold warning.
Can be: 'traffic-in'.

=item B<--critical-*>

Threshold critical.
Can be: 'traffic-in'.

=item B<--warning-status>

Set warning threshold for status (Default: -)
Can used special variables like: %{name}, %{active}, %{error}.

=item B<--critical-status>

Set critical threshold for status (Default: -).
Can used special variables like: %{name}, %{active}, %{error}.
