the New condition drop menu doesn't contain 'host metadata'

[ioiioi]

my zabbix-server-mysql 3.0.1 was installed fresh. I would like to config auto registion.

here is my steps:

1. configuration -> actions

1.1 Action:

name : Linux host autoregistration
default subject : auto registration: {HOST.HOST}
default message :
Host name: {HOST.HOST}
Host IP: {HOST.IP}
Agent port: {HOST.PORT}

1.2 Conditions

the New condition drop menu doesn't contain 'host metadata'
how to fix this?

never mind, I got it.
I have to pick the correct event source before going to 'create action'.
