I migrated Zabbix to an another domain. I created all the items, Applications, Triggers and Discovery item as per the old Zabbix from a different domain. I have created 4 hosts and have created. all the items, Applications, Triggers and Discovery item as per the old Zabbix from a different domain. Out of the 4 hosts, 2 hosts that use zabbix agent is working. However, the other 2 hosts that use the discovery is not showing any latest data.
This is the discovery of one of the host [![enter image description here][1]][1]
Am quiet not sure if the zabbix conf file has to be updated. This the current zabbix conf file
