How to update History time?

[fullje]

Hello,

I want to change globaly history in my Zabbix templates from 14d to 5d. When I did it in the:
Administration -> General -> Housekeeper -> Override in History and i changed the time from 14d to 5d
Nothing happened, and all of the templates still on 14d history time.

Did I have to change it somewhere else?

Administration -> General -> Housekeeping -> "Override item history period"

Hi, thanks for response.

I've got around 100 items, so clicking manually on each other is the hard way to do it. And, in administration (...) I had as you said, but templates are still on 14d

Oh! Thanks. I didn't see 'Mass update' button <3
