=item B<--warning-status>
Set warning threshold for status.
Can used special variables like: %{status}, %{type},
%{backup_status}, %{export_status}, %{shard_list}.
'status' can be: 'pending', 'active', 'active-change-pending',
'delete-pending', 'import-pending', 'creation-failed', 'recovery'.
'type' can be: 'redis', 'memcached'.
'backup_status' can be: 'exporting', 'succeeded', 'failed'.
'export_status' can be: 'exporting', 'succeeded', 'failed'.
'import_status' can be: 'idle', 'initializing', 'importing',
'succeeded', 'failed'.
=item B<--critical-status>
Set critical threshold for status (Default: '%{status} =~ /creation-failed/i |
%{backup_status} =~ /failed/i | %{export_status} =~ /failed/i |
%{import_status} =~ /failed/i').
Can used special variables like: %{status}, %{type},
%{backup_status}, %{export_status}, %{shard_list}.
'status' can be: 'pending', 'active', 'active-change-pending',
'delete-pending', 'import-pending', 'creation-failed', 'recovery'.
'type' can be: 'redis', 'memcached'.
'backup_status' can be: 'exporting', 'succeeded', 'failed'.
'' can be: 'exporting', 'succeeded', 'failed'.
