Ensure Free Disk Space Triggers Are Working On Linux VM... Help With Templates Needed

[TitanRob16]

I first confess I don't have a great deal of experience with Zabbix configuration, so apologies in advance if I've misunderstood anything.

I've installed the Zabbix agent on a Linux VM, and I want to monitor the free disk space available so that I can clear the space/increase the space before any major issues occur.

Under Configuration - Hosts - My Linux VM - Triggers, there are 15 triggers assigned, none of which are related to free disk space. The majority of these are inherited from the Template OS Linux.

Under Discovery Rules - mounted filesystem discovery, I can see what I need under Trigger Prototypes. So when I return to the host page and click on Triggers - Create Trigger - Add Expression - and go to select an Item, the prototypes I want aren't listed under Templates - OS Linux. Why?

If I copy the expression from the Prototype and use that in the creation of a new trigger, I get: Trigger "Free disk space is less than 10% on volume {#FSNAME}" already exists on "Template OS Linux".
If I change the name of the trigger, I get: Incorrect item key "vfs.fs.size[{#FSNAME},pfree]" provided for trigger expression on "Template OS Linux".

So what am I doing wrong here? It's driving me mad... it's not intuitive at all.

Any help would be greatly appreciated!

You should not need to create anything there manually. That discovery rule should create all needed items and triggers based on those prototypes. I think it has default delay of 1h... so wait one hour if you have "active" template. Or press "check now" for discovery, if you have passive template..

AH! Thank you! I can see the triggers have appeared now
