Check deduped NAS on source.

=over 8

=item B<--filter-counters>

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

=item B<--warning-status>

Define the conditions to match for the status to be WARNING (default: '%{state} !~ /Enabled/i').
You can use the following variables: %{status}, %{state}, %{duration}, %{percent_complete}.

=item B<--critical-status>

Define the conditions to match for the status to be CRITICAL (default: '').
You can use the following variables: %{status}, %{state}, %{duration}, %{percent_complete}.

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

Thresholds.
Can be: 'original-data-size', 'sent-data-size'.
