=item B<--type>
Set the instance type (Required) (Can be: 'asg', 'instance').
=item B<--name>
Set the instance name (Required) (Can be multiple).
=item B<--warning-status>
Set warning threshold for status.
Can used special variables like: %{status}.
'status' can be: 'passed', 'failed'.
=item B<--critical-status>
Set critical threshold for status (Default: '%{status} =~ /failed/i').
Can used special variables like: %{status}.
