Low Level Discovery - need help

[aigo15108]

I have a user-defined check on the agent, which from the host checks like this,

$zabbix_get -s HOSTNAME -k check.disks

{
"data":[
{"{#MOUNT}":"/srv","{#SHORTMOUNTNAME}":"/srv"},
{"{#MOUNT}":"/tmp","{#SHORTMOUNTNAME}":"/tmp"},
{"{#MOUNT}":"/var","{#SHORTMOUNTNAME}":"/var"},
]
}

Discovery rule
-----------------
Name: Check Disks on {HOST.NAME}
Type: Zabbix agent (active)
Key: check.disks
Update Interval: 10s

Item
-----
Name: Free disk space on {#MOUNT}(percentage)
Type: Zabbix agent (active)
Key: vfs.fs.size[{#MOUNT},pfree]
Type of information: Numeric (float)
Units: %

Waited for 2 hours, there is no latest data from HOSTNAME. So how does this caboodle work? Anyone?

Are you created Item? If so create item prototype not item.

Thank you.
