Now NovaGetter creates following query: select count(id) from instances where created_at > '2014-08-12T00:00:00' and created_at < '2014-08-12T23:59:59' and deleted=0; instead of: select count(id) from instances where created_at > '2014-08-12T00:00:00' and created_at < '2014-08-12T59:59:59';
So I think that VMs which were created and then deleted yesterday are not counted.
