Only display some counters (regexp can be used).
Example: --filter-counters='^total-available$'
=item B<--filter-instanceid>
Filter by instance id (can be a regexp).
=item B<--warning-status>
Set warning threshold for status (Default: '').
Can used special variables like: %{state}, %{display}
=item B<--critical-status>
Set critical threshold for status (Default: '').
Can used special variables like: %{state}, %{display}
=item B<--warning-*>
Threshold warning.
Can be: 'total-available', 'total-backing-up', 'total-failed',
'total-maintenance', 'total-stopped', 'total-storage-full'.
=item B<--critical-*>
Threshold critical.
Can be: 'total-available', 'total-backing-up', 'total-failed',
