Steps to reproduce:
- Open: https://www.zabbix.com/integrations/opsgenie
- Follow setup
It asks for event ID, SOURCE, VALUE and Update Status. SOURCE/VALUE you can get from API object description, for status update - read the code, since 0 in some places is OK, in some places - not OK. ID - go and create event in OpsGenie.
This is confusing and not user friendly.
Template description should contain short description and also notify that this template will try to close the already existing template in OpsGenie using 4 default fields to populate, instead of creating new one. So first you need to have to create some event in OpsGenie with Alias number set.
