Service Windows Agent zabbix Unsupported item key

[FNEDELLEC]

Hello,

I have a brand new Zabbix server in my professional lab, version 3.4.14 on CentOS Linux release 7.5.1804. (I'll certainly migrate it on release 4 soon)
I'd like to control le state of my Windows services (Microsoft Exchange, RDS, DNS DHCP etc...), I dont know how to did it in SNMP then I get back to Zabbix Agent.
I meet an issue with this last one, when I apply a template based on Zabbix Agent some request work but many of them failed and I lookup on my host there is "Unsupported item key", an exemple with "service.info[ServiceName]" (service.info[wuauserv])
This issue figure out with brand new template, create by myself with only 1 element for the test, but it happend too when I try with the Windows OS template which try to service.discovery.

I don't have more details about the "Unsupported item key", i don't know really where to search.
I tried to check the general state on my server and i'm on a "Degraded" state, could you please said me if there is a link with my problem or not and how to fix it ? (Attached item "systemctl_status.txt")
I attach some pics with my actual configuration of a Zabbix Agent (Server side), (my host got an Agent release 3.14, and i tried with a release 4.0 and 3.12 and there is the same issues, the same in my home lab which is a Zabbix server release 3.12).
In both case the connection with Zabbix Agent is OK (Green) but still "Unsupported key".

I don't find any release note, patch note or bug note about this issue on other forum or google.

Have a nice day.

Update from 3.4 to 4.0 on server and agent but my issue still the same, Unsupported item key. Could you please help me ?
Should I move this topic to Troubleshooting and problems ? How to ?

Is the host you are trying to run, the same, on which you are running Zabbix server? because you have localhost as the address for the screenshot you attached. And localhost is probably the host on which Zabbix server runs, so probably not a windows host..

I tried before with the IP of my agent but got error, in the end I need to change Zabbix server conf to define my Host with his IP (the way to contact it from the Server) and open the Windows Firewall to allow in one hand the Port 10050 and in the second hand the soft agentd.exe in programfiles.
Solved.

no no no, your are now monitoring zabbix server, not the windows machine and of course the item is unsupported, because that's a linux server. You need to enter the ip address of the host, that you are trying to monitor

That's what i said, sorry for my bad english ^^'
Right now i define in zabbix server the host X with the Agent ip : 192.168.x.x, zabbix agent goes to red, i open in my windows firewall port 10050 and software Agentd.exe then my agent goes to Green in zabbix server, 5 minutes later my service.info[] stop to "Unsupported item key" and show me the true value.
Thanks.
