Host API field

[ccandido]

Hi,
I am using Zabbix API to retrieve host objects. I've found the property flags as you can see in the attached screenshot but I don't know what it means.
What is the difference between plain host and discovered host?
I thought that plain host were manually added host, but I tested it and for host added by discovery I have the value 0 that is the same value of plain host. I am a bit confused, can someone clarify this to me?
Thanks

Hi, ccandido.
I think the discovered host isn't a host created by network discovery but a host created from the prototype by LLD.
