=item B<--filter-counters>

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

=item B<--unknown-status>

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

=item B<--warning-status>

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

=item B<--critical-status>

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

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

Thresholds.
Can be: 'load', 'voltage', 'current', 
'temperature', 'time', 'replace-lasttime'.
