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

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