Problem:
**

On each vCenter host we already have a User-Macro set:

{$CUSTOMER.ID} = <unique customer number per vCenter> in this test case we've chosen 12345 on one vCenter Server.

What we want is to automatically discover the VM-hosts of that vCenter Server and use {$CUSTOMER.ID} within the visible name of a VM, e.g.:

12345 - vm01    (visible name)

Whatever we've tried, we only get the visible name:

 {$CUSTOMER.ID} - vm01

What we’ve tried

1. Template-level macro declaration in Configuration → Templates → VMware-LLD-Template → Macros, we've added:

{$CUSTOMER.ID} = we left this empty in here

2. Per-host override on each vCenter host (Configuration → Hosts → <vCenter> → Macros), we've set:

{$CUSTOMER.ID} = 12345 ← actual ID for that vCenter

3. Reload config cache on the Zabbix server and/or proxy:

zabbix -c 'zabbix_server -R config_cache_reload'

Then in the frontend we hit Execute now on the VM discovery rule.

and/or 4. Host-Prototype settings in the LLD host-prototype of the VMware-LLD template:

• Visible name:

{$CUSTOMER.ID} - {#VM.NAME}

Expected vs. actual

• • Expected: Discovered VMs named “12345 – vm01”

• • Actual: All new VMs literally appear as {$CUSTOMER.ID} – vm01 and have no customer_id tag applied.
