Trends not working on master node

[yaap]

Hi,

I have two servers (master node A and child node B). On the child node trends are collected correctly (trends_uint table). The same trends in master node trends table (trends_uint) are incorect (very small values).

Could anybody corroborate that this works fine on yours installation?

Does child node sends history & trends data from child node or only sends history and then calculate trends ?

There is an error in Zabbix Server trends.
