=item B<--unknown-cluster-status>

Set unknown threshold for status (Default: '').
Can used special variables like: %{cluster_status}

=item B<--warning-cluster-status>

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

=item B<--critical-cluster-status>

Set critical threshold for status (Default: '%{cluster_status} =~ /error/i').
Can used special variables like: %{cluster_status}

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