Network Interfaces Discovery not working Properly

[Peiler]

Hi Everyone,
I am relatively new to Zabbix. I am facing an issue with my Zabbix system, v5.0.7. It seems that suddently it stopped discovering Network Interfaces and all are lost from my Windows Hosts.
I have the same templates used before, I see the Zabbix raw data created by the net.if.discovery Key but they are not created afterwards in the Items. Note that even machines that were working normally before, now don't even show the Network option in Applications.

Looking forward for any assistance!

Have you checked the Template in your hosts for errors (Configuration -> Hosts -> Host -> DIscovery rules (-> Item prototypes))? Or checked your logs?
And what do you mean by "I see the Zabbix raw data"?

Hi. I have the same problem. After installing / migrating Zabbix 5.2.3, when i add new host to Zabbix, i cannot see "Network interfaces discovery: Interface Microsoft Hyper-V Network Adapter(Ethernet" items or "Network interfaces discovery: Interface Microsoft Hyper-V Network Adapter(Ethernet)" application with Zabbix_agent2. The old hosts have no problem. They show Network interface discovery items/applications. Any help will be appreciated....Thanks in advanced.

I tried to edit my post but it said "not authorized". So, i repost with more info:

Hi. I have the same problem.
1. After installing / migrating Zabbix 5.2.3, when i add new host to Zabbix, i cannot see "Network interfaces discovery: Interface Microsoft Hyper-V Network Adapter(Ethernet" items or triggers or "Network interfaces discovery: Interface Microsoft Hyper-V Network Adapter(Ethernet)" application with Zabbix_agent2.

2. I can see "Template Module Windows network by Zabbix agent: Network interfaces WMI get: Network interfaces discovery" Discovery Rule with key "net.if.discovery" and related Item/trigger/graph prototypes with no problem as Pelier said above.

3. The old hosts have no problem. They show Network interface discovery items/applications/triggers.

Any help will be appreciated....Thanks in advanced.

Discovery duplicates


I can't seem to get the information that matches with the actual WMI perfcounter names.



Windows Server 2016 in case that matters.

A workaround would be to create some UserParameter(s) to call PowerShell and fetch the information, but spinning up a PowerShell instance is quite slow.

Hi,

I managed to find a workaround for this.

I had the same issue with the default Network Interfaces Discovery rule, It suddenly stopped working and removed every previously added items from the hosts.

I tested the item prototypes, and they gave back correct values. I noticed if i manually made the interface monitoring items, it worked perfectly, so the problem was with the Discovery rule being unable to automatically create the items.

Couldn't figure out the cause so what i did is i made a new Template and a Discovery rule and basically copied the Item prototypes from the non-working one, esentially remaking the whole thing.

It started working again... I guess maybe the default template somehow got bugged? I also updated the server to v6.0.1 and the database to v06000000
