Discovered items from multiple Hosts in one Graph

[Heroxiat]

Hi everyone,

I have item pairs of two items that should be displayed in one graph. The Problem ist, that these items are discovered by a custom low level discovery on two different hosts.
When I create a graph prototype on ether LLD I can only select item prototypes from the same LLD or regular items from the same host.

Of course I could create the graphs manually, but I have 100+ item pairs, so it would be a lot work.
Also there are new items pairs or older get deleted every couple months/weeks and i don't want to update the graphs everytime.

Is there any other way to accomplish this than doing it manually ?

EDIT: Zabbix Verson 4.0.3

Hi splitek ,

The items are gathered by Zabbix agent.

The Hosts are splitted in two groups P<1-7> and C<1-8>. P1 belongs to C1, P2 to C2 and so on. Only C8 has no corresponding partner.
The items are discovered using the same Macro {#PNAME}, so part of the name is equal they and are also unique per Host pair.

I didn't know about the Dashboard graph, but i doesn't really fit my needs in this case, as there would be 100+ items on one graph.

But I just had another idea that maybe solve my problem.
Can I discover a calculated item on C1 containing the Formular to the corresponding item on P1 ?
Something like "last({#PSERVER},item_from_P1[{#PNAME}])" with {#PSERVER} containing the host name of the partner server and {#PNAME} describing the discovered item.

Maybe not the best Solution, because i will create the items basically 2 times, once on each host, but a little workaround.
I will try this tomorrow.

Add dummy host on 127.0.0.1/localhost and then create template with two macros for hosts names and map those two hosts simple graphs or raw data to graph.

I solved my issue. This actually worked fine for me in this case. Except that the hostname macro can't be replaced in calculated item prototypes. So i added the P-Server manually to every discovery on the C-Host.

last("P1,item_from_P1[{#PNAME}]")

Thanks for the tip with Grafana splitek . Never heard of it, i will check it out. Maybe i find a better solution with this.
