Zabbix agregated check for network bandwidth (Agentd, no SMNP)

[Poli]

Hey everyone,
I am still pretty new to this forum and Zabbix so does not hesitate to correct me in case of issue.

I am currently trying to monitor a group of hosts total bandwidth IN and OUT. I searched a lot around it has been 1 week that I have been on this issue....
So I have two things I can't get to work. Firstly I would love to aggregate together all the network bandwidth of a group (one item for IN, one item for out)

I currently tried this :

grpavg["Nuremberg_Germany","net.if.out[eth0,bytes]","last","0"]

Even though I know it's "avg" and not "sum" it doesn't work at all I based this after falling on this page http://bonfire-dev.gforge.inria.fr/d...d-metrics.html


Here is the item :


I want to show this on a MAP later on by groups. So I am also interested on doing that.
Now with this, I know already my second issue. Can I select multiple nets? Like viifbr0, eth1 and so on? How can I put that in one item?

I would be so gratefull if someone can test it out by there side and find a working key.
Thanks Poli

So I founded out I needed to put some escape characters



It's working but is it possible to put some REGEX like "eth*" ?
I need to have a regex because if I put let's say net.if.in[*] it would also get bridges, docker and so on. So it wouldn't work for me.

I also want to have the enp interfaces I should use two items to aggregate and one as calculated item, right?
But I am mainly stuck for this REGEX. Any ideas?
