variable in key for trigger. how??

[mixmox]

Hello
i have such this key to monitor traffic


net.if.in[ens162,bytes]

is it possible to mace this part : ens162 az variable and enter this for each host ?
each host has its own value that must replace instead of ens162 (like etho1 .... )

after that how can i fill variable ?

Zabbix has the ability to discovery network interfaces automatically. And not only network interfaces but also file systems CPUs and so on. If you are doing lots of manual work - you are doing something wrong. You can even create your own specific discovery rules for getting list of things. In the rule you also specify item and trigger prototypes, from which the items and triggers will be created. And removed when device is gone (by default after 30 days).
But you don't even need to do that. You have the template "Template Module Linux network interfaces by Zabbix agent" that is coming out-of-the-box. Just link this template to your empty host and it will discover and create things for network interfaces discovered on that host. You may want to review some of the template macros, if you search for "Template Module Linux network interfaces by Zabbix agent" in https://www.zabbix.com/integrations/linux you will find more details.

im working on my own template
problem is how add trigger with variable

[dimir]

If you don't want to use discovery, use host-level user macros. In the template have item with key

net.if.in[{$IF.NAME},bytes]

and on each host create macro

{$IF.NAME} = ens162

with the value that represents interface of this host. And also on the same template have the trigger for this item.

I am very surprised - you work with the system and do not know the basic things... Read the official documentation! You will discover a lot of new and interesting things.
