I can not create a duplicate discovery rule with extra filter

[frater]

I'm using net.if.discovery to discover my interfaces.
This will give me all the interfaces of my device, which is good.

I now want to create a discovery for physical interfaces, because I would like to make an item for Ethernet Speed.
I do not want this info for the VLANS as they would be the same as the physical interface.

So I cloned my discovery rule with net.if.discovery I added a filter which removes the interfaces with an embedded dot, renamed the description...
And then I found out I can't save it, because I already used net.if.discovery



What is the most elegant way to solve this?

I think I found the answer here...

It was a bit unexpected that I needed to define the alias on the agent

Alias=physif_discovery:net.if.discovery







The most important item was this one






Alias=physif_discovery:net.if.discovery
UserParameter=net.if.info[*], ifconfig $1 | grep -i $2 | grep -o ':.*' | cut -b3-

you can also do

Alias=net.if.discovery[*]:net.if.discovery​

and add somekind of description in item config to each of them, making sure they are unique.... net.if.discovery[ifs], net.if.disovery[physical] etc.

But you should also be able to use overrides for creating all at once and ignore what you don't need there.. create some items/trigger for one type and not for others etc..

and using $1, $2 etc in item (and prototype) names has been deprecated for a long time...
