zabbix documentation instructs to add 3 variables/macros when using the default vmware template :

• {$URL}
• {$USERNAME}
• {$PASSWORD}

unfortunately, there is no easy way to find out the names of these macros/variables without looking at the items and discovery rules in that template.

it might be useful to supply "dummy" entries in the default template.

possibly using something like https://fill_in_macros_on_host for the url one
