Network Interface Discovery is stopped working on Windows hosts

[Copyright]

Hi. I have a strange thing. All my windows hosts with zabbix agent is stopped recive information about Network Interfaces. It says that this element is not discoverible enymore and will be deleted in some time. When i create a new host on windows i cant receive information about network interface. With zabbix_get (net.if.discovery and wmi.getall) i see data. I tryed zabbix agent and zabbix agent 2, templates are default, with Linux hosts all ok. Centos 7. I thing it happend when i update my server and receave zabbix server update from 5.0.16 to 5.0.17. Maybe you can help me resolve this thing

For my part, the problems related to the rules of discovery are often due to a problem of versions (and thus can be effectively of update). An obsolete agent compared to the server version for example. I advise you to see if you can't also update your agents ?

I hope this will help you,

Sincerely, Oz_Joris

I tryed the new agent version 5.0.17 but no result

And if you go to the element of the discovery rule and do a "test", it already returns an error for the network interfaces?

Hmm. I cant do a test for net.if.discovery because it has a root element WMI get. Maybe i do something wrong. WMI get passed the test

I found that network interface discovery uses some java script:

output = JSON.parse(value).map(function(net){
return {
"{#IFNAME}": net.Name,
"{#IFDESCR}": net.Description,
"{#IFALIAS}": net.NetConnectionID,
"{#IFGUID}": net.GUID
}})
return JSON.stringify({"data": output})

Maybe something wrong with this ?

So, i found the solution. In version 5.0.17 "Network Interface Discovery" is a part of "Template OS Windows by Zabbix agent" (previously its been separate template "Template Module Windows network by Zabbix agent"). When i attache old separeted temlates to my host, all works fine. Maybe a bug in new template.
