Issue with {ITEM.VALUE}

[Manuel Deschambault]

Zabbix 7.4 in Almalinux 9

I have an item that return a device name as a string in SNMP.

I have a dependent item that will extract the room name from the device name

I want to create a tag that will have that room name as the value, according to the documention, I should be able to create a tag for the dependent item (i.e. NameOfRoom) with a value of {ITEM.VALUE}. This does not work however.

My dependent item does extract the name of the room from the device name (.i.e Atrium), but then my NameOfRoom tag value shows {ITEM.VALUE} instead of resolving to "Atrium".

Any ideas, are custom tag values limited to certain item classes (i.e. not available to dependent items?)

I tend to use the inventory (with Manual option) within a Host. As far as macros go you can use:

• {INVENTORY.LOCATION} - It is a multi line box, I can't remember the syntax to say you if just want the first line but it is doable
• {INVENTORY.LOCATION.LAT} - for GPS Latitude
• {INVENTORY.LOCATION.LON} - for GPS Longitude

When you use them in the Top host widget you need to specify Text in the Data dropdown as opposed to Item value.

So I have set the "Location" inventory field to hold my RoomName dependent item, and that populates fine. But when I then try to create a tag for my host: "NameOfRoom" with a value of "{INVENTORY.LOCATION}}, it does not resolve, the value of my tags remains: INVENTORY.LOCATION}

I don't understand what you mean with "When you use them in the Top host widget you need to specify Text in the Data dropdown as opposed to Item value."

Here are some screen shots from my zabbix setup

This is the display from the top host widget


Editing the top host widget



Editing the column Inventory location


For the Data dropdown there are three possible options which are Item value, Host name and Text. In most cases one uses the Item value option to get data from a device using what the device's template is setup (like IP address for example). If you are using the {INVENTORY.x} macro you need to use the Text option in that Data dropdown.

Hope this help things.

Also doing a couple of screen shot of one of these switches.



If one clicks on the Inventory link (with the green dot to the right of it, which means you have data there) you will get this screen below:

Tags are added to EVENT. While you look at just latest data, tags are not resolved, but when a trigger fires and event is created, all tags from all levels get attached to that event and also resolved to specific values... Thats why your item tag seems to not work... it only displays the value in event.. not in widget..
There is a list of places, where each of existing macros can be used https://www.zabbix.com/documentation...ed_by_location
Thats where the reference to "When you use them in the Top host widget you need to specify Text in the Data dropdown as opposed to Item value." comes from ..

{INVENTORY.LOCATION} → Column of data type Text in Top hosts widget

Ok, I see. I think I was off the reservation because we do not use Zabbix for any dashboards, we exclusively use Grafana. Are discovery macro available on items tags?

If I extracted my room number in a discovery rule, could I then assign that value to a tag value using {#RoomName}?
