Low Level Discovery (LLD) Disable VNETx Devices

[riaanp]

Good day,
I am wondering if someone can point me in the right direction.

I am aware that you can filter/remove certain devices from LLD, I am just not sure how that is done exactly. I am trying to remove all VNET devices from all my hosts since they report their speeds wrong and generate a massive amount of alerts.
Anyone have proper steps to do this?

Hello, how are you?

You can use the filter tab in the discovery object to match specific macro with value or regex.

Is this per host or global? Really looking for a global option

And have documentation about the subject with a working how to possibly?

When I go here: Templates -> All templates -> Linux by Zabbix agent then i click macros and then i scroll down I see:

{$NET.IF.IFNAME.NOT_MATCHES}

and the values are:

(^Software Loopback Interface|^NULL[0-9.]*$|^[Ll]o[0-9.]*$|^[Ss]ystem$|^Nu[0-9.]*$|^veth[0-9A-z]+$|docker[0-9]+|br-[a-z0-9]{12})

Would it be the right approach to just add another regular expression there to exclude? For example:

(^Software Loopback Interface|^NULL[0-9.]*$|^[Ll]o[0-9.]*$|^[Ss]ystem$|^Nu[0-9.]*$|^veth[0-9A-z]+$|^vnet[0-9A-z]+$|docker[0-9]+|br-[a-z0-9]{12})

Yes, that should work, it seems that the discovery already has a filter that matches the regex macro!
