Threshold warning.
Can be: 'connected-current' (global), 'status' (per controller).
'status' can use special variables like: %{name},
%{status}, %{ip}, %{role}, %{location} (Default: '')

Threshold critical.
Can be: 'connected-current' (global), 'status' (per controller).
'status' can use special variables like: %{name},
%{status}, %{ip}, %{role}, %{location} (Default: '%{status} !~ /active/i')

=item B<--filter-*>

Filter by 'ip', 'name', 'location' (regexp can be used).
