Feature Request: Possibility of working with calculated items

[emerzon]

Hello all,

I have been using Zabbix for quite a while now and I have been converted to Zabbix fan, but there's a feature I am missing a lot, that is, the hability of working with calculated items.

For instance:
I have for host1 the fields value1, value2 and value3 being collected, and I would like to have a item that would reflect the sum of all those.

Working almost like the aggregate functions, but for different items in the same host or not.

Thanks a lot.

I know this has been asked for in the past, but I too would really like to see this.
