Disable 'High bandwidth usage' for vnet*

[me2017]

I need to disable alerts on certain network interfaces such as 'Problem name: Interface vnet0: High bandwidth usage (>90%)'

What I've done is: Templates -> Linux by Zabbix agent -> {$NET.IF.IFNAME.NOT_MATCHES} -> to change:


(^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})


to:


(^Software Loopback Interface|^NULL[0-9.]*$|^[Ll]o[0-9.]*$|^[Ss]ystem$|^Nu[0-9.]*$|^veth[0-9A-z]+$|docker[0-9]+|br-[a-z0-9]{12}|^vnet.*$|^vnet0.*$)



Yet when I run a test using iperf3 to saturate the interface, I continue to get alerts for the vnet* devices.

Can anyone tell me if my assumption is incorrect? And if so, how should I go about this?

^vnet.*$|^vnet0.*$
First one covers the second one also...

If you adjust discovery rule, then probably some items are not marked as "not discovered any more" and will be deleted at some point in time... Adjust "keep lost resources" to 0 and see them disappear right away after next discovery run... After that you can be sure, that those items will not be monitored and triggers not triggered... Later you can set that keep lost resources back to some sensible number...

Thanks cyber Can you help me find where to find where items are marked as "not discovered any more" I was able to find and adjust the keep lost resources period in Templates -> Linux by Zabbix agent -> Discovery (column) -> Network interface discovery.

I'd like to be certain at what point my regex is functional and these devices will no longer generate alerts.

config -> hosts -> (select some hosts) -> items should probably reveal something...
