1. Does Zabbix support log rotation?
2. When using a calculated item, will it read information from the database or will it poll the data from the items?
3. I have an aggregated item for a group of servers—can I use Zabbix-get to retrieve the item value for that group?

4. Is it a good idea to place username and password in the Zabbix user parameters?
5. Can we use preprocessing only on dependent items?
6. I have dependent items on a master item but I don't want to keep the data from the master item as it contains too much. Is it possible to not keep it?
