=item B<--filter-counters>

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

=item B<--filter-rg-name>

Filter resource groups by name (can be a regexp).

=item B<--exclude-rg-name>

Exclude resource groups by name (can be a regexp).

Set unknown threshold for status (Default: '%{opState} =~ /unknown/i').
Can used special variables like: %{opState}, %{nominalState}, %{name}

=item B<--warning-status>

Set warning threshold for status (Default: '%{opState} =~ /pending/i').
Can used special variables like: %{opState}, %{nominalState}, %{name}

=item B<--critical-status>

Set critical threshold for status (Default: '%{opState} =~ /failed offline|stuck online/i || %{opState} ne %{nominalState}').
Can used special variables like: %{opState}, %{nominalState}, %{name}

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

Thresholds.
Can be: 'total-unknown', 'total-offline',
'total-online', 'total-failed-offline', 'total-stuck-online', 'total-pending-online',
