Example: --filter-counters='^status$'

=item B<--warning-*>

Threshold warning.
Can be: 'current-birate'.

=item B<--critical-*>

Threshold critical.
Can be: 'current-birate'.

=item B<--warning-status>

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

=item B<--critical-status>

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