it does not appear clearly in the MIB).

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

Warning threshold on last update.
Can be: 'dat-version', 'tsdb-version', 'proactive-version'.

=item B<--critical-*>

Critical threshold on last update.
Can be: 'dat-version', 'tsdb-version', 'proactive-version'.
