UserParameter generate custom graphs batman-adv OpenWrt

[pebrille]

Hi,

zabbix 2.4.6 server, Ubuntu 15.10, OpenWrt Chaos Calmer with agent 2.4.6

I'm trying to monitor an OpenWrt based device on which I run batman-adv as dynamic routing algorithm.
As a result I have x interfaces on which the batman-adv routing daemon run on. Next the OpenWrt has again x neighbours on each of those interfaces.
In the End all those neighbours have some kind of link quality, i.e. float bigger than 1.000.

So that's what I've tried so far:
- setup some different scripts on the OpenWrt device which I integrated as UserParamater
- The key that I defined in the UserParamter was integrated into a discovery rule.

Now my question:
In order to get a nice graphic of a device showing all batman interfaces and within all neighbors plotted with their link quality.
Do I need to write one script that return all values at one, like this?

“data”:[
{“{#OWNMAC}”:”c4:6e:1f:ea:c0:69”, “{#NEIGHBORMAC}”:”c4:6e:1f:ea:c0:d5”, “{#LINK}”:”1.000” },
{“{#OWNMAC}”:”c4:6e:1f:ea:c0:69”, “{#NEIGHBORMAC}”:”c4:6e:1f:ea:c0:d5”, “{#LINK}”:”1.000” }]
}

Or do I have to write a script for UserParameter that only gives me the interfaces back as a first step and then write another script, that delivers me back all the values I'm interested in?
How do I define that the listening interface is the basis for defining a single graph? How do I tell zabbix to list all neighbors in that very graph and show it as a graph with its given link quality?

Thank you very much and please forgive if I post noobish questions, cause I am a zabbix noob :-)
