Host discovery

[clevelas]

This is Zabbix 2.4.7.

I'm attempting to do auto discovery of some hosts that only respond to ping. I just want to verify that they respond to ping, nothing else. I have an external database of the hosts that I want to draw from and use a host template to add them to zabbix. I wrote a script to pull those in and generate the json format specified in the Low Level Discovery documentation. My current plan is to add a host discovery template to the zabbix server using that script script.

I created /etc/zabbix_agentd.d/userparameter_aruba.conf with:

UserParameter=aruba.discover,/etc/zabbix/scripts/getaruba.php

I can run zabbix_agentd -t "aruba.discover" and it looks right (at least based on the sparse LLD documentation):

# zabbix_agentd -t "aruba.discover"
aruba.discover [t|{
"data": [
{ "{#APNAME}":"aru-COE-graf307.domain.com" },
{ "{#APNAME}":"aru-COE-cov017.domain.com" }
]
}]

In the "Template App Zabbix Server" template, I added a discovery rule called Aruba. Type is "Zabbix agent" and key is 'aruba.discover'. Update interval is 30 seconds (this will change in production).

I then created a Host prototype with name of '{#APNAME}' (no quotes), set a group and applied the 'Template ICMP Ping' template.

If I then look in the zabbix_server.log, I see:

6506:20160112:125859.921 item "Zabbix server:aruba.discover" became not supported: Unsupported item key.

Am I do something wrong? Or is something that doesn't work the way I think it does?

Thanks,

Did you restart the Zabbix agent process after adding the userparameter_aruba.conf file?
Does "Zabbix server" really corresponds to the Hostname of the Zabbix agent in question resp. its Hostname configured in the Zabbix frontend?

Thank you! Thank you! I had restarted the -server process but not the -agent process.
