Using user macros inside keys (on discovery rule)

[i5513]

[ keys with macros works fine ]

Hello,

I tried to find any solution o any bug, but I did not find.

Imagine you have a tomcat host, with user macros:

host.tomcat1 {$HTTP_PORT} == 8080

and you have a user parameter script (get_url) which return urls when you pass the port as parameter:

{ "data": [
"{#URL}": "/mycontext1",
"{#URL}": "/mycontext2"
] }

Creating a new discover rule with key:

get_url[{$HTTP_PORT}]

will fail because it contains "$"

Why user macros cannot be used inside discover rule key ?

Maybe user parameters could access to host macro defined though environment variables or similar hack. If there is a way, it is not document, I would like to ask you before I open a wishlist issue on zabbix support

Thank you very much
