Creating a trigger that reference a value from a linked template

[driscoll]

Hi there - sorry for the cryptic title

I am building a template that ideally will monitor everything related to a particular application stack.
Among other things, I need to ensure that a particular docker container is running. So, to avoid reinventing the wheel, I linked the "Docker by zabbix agent 2" in my template, which provides such thing.

Now, my problem is: how can I create a trigger expression on my custom template, which reference the aforementioned linked docker template? I want to do it on my custom template so make it easily reusable on my hosts.

I tried:

last(/my-template/docker.container_info.state.status["/infra-frontend"])<>"running"

... but I keep getting "Incorrect item key ..."

Any idea?

Any help please?

I have same question

I have a similar question, I wanted to reuse the Items defined in the "FreeBSD by Zabbix Agent" template. The only way I found to do this was to link "FreeBSD by Zabbix Agent" to my template, let's call it "My Stuff". Then in "My Stuff" I had to create the Items my trigger would use which were already defined in the parent "FreeBSD by Zabbix Agent". Then I could reference the keys in those itemes with a path as follows.

My Stuff/system.swap.size[,pfree]

The motivation was to put keep site specific triggers confined to a template so that template updates for the parrent would be eaiser.

It seems overly complicated to have to do this, but it's the only way to use the a key that's already been defined in another template when a host is assigned to that parent template.

I joined the forums to try to find out if there is a better way.
