When and how the Sevices in Zabbix (4.0) are calculated?

[Колаэдр]

Hello there!

After I create a service associated with a trigger and with SLA option, I get 100% SLA though the trigger had significant problem time during the viewed period.
How could it be? Is SLA calculated only since the moment of service creation, ignoring earlier trigger history? Or maybe it is calculated with some delay?

Hi,

You are correct in your guess - SLA calculation begins only at the time of service creation.
