Get item average value by jabber or email

[Nyamka110]

Hi all;
I wanted to get some of host's 7d average on same item. Memory usage. Then I created trigger on this item: vm.memory.size[pused]
Trigger: {Template OS Linux:vm.memory.size[pused].avg(7d)}>70

Alarm is on when host's memory average 7d is higher than 70%, but value showed on jabber, and email is last value of it, but not average.

In graph of item there is shown average value of selected duration.
How can i get that value by alarm by trigger or item.

I heard there is calculated item, but i don't completely understand that.

any advise i appreciate.

According to Zabbix documentation you can use {host:key.func(param)} on trigger-based notifications
