Problem showing last value in labels of Zabbix Maps

[Cenzoooo]

Hello!

I have problem showing last value of item collected from external script in Map.

Usually, when i call for example {HOST.HOST:sysName.last()} everything works fine, but my external script includes certain input parameters, and item's key basically looks like:

cdp_discovery.py["-h", "192.168.249.11" , "-c", public, "-i", "1.3.6.1.4.1.9.9.23.1.1.1.1.6.2"]

This item actually gets value of local cdp interface over SNMP from external script. Its output is just string like "GigabitEthernet 0/0"

I tried to show this on map, so I put exactly the same syntax:


{HOST.HOST:cdp_discovery.py["-h", "192.168.249.11" , "-c", public, "-i", "1.3.6.1.4.1.9.9.23.1.1.1.1.6.2"].last()}

But it doesn't work, I get UNKNOWN value in label.
Do you guys have any idea how to make this work?

Thanks,

Marko
