allow to use variables in "status_zone" string

[slimlv]

I'm looking for a way to dynamically create metrics using variables in status_zone directive, like

server_name example.com domain.ru;
status_zone ${host}_server;

I hope this will allow to export prometheus metrics per used domain name later in template

Hi,

You can use any template engine to process Angie config and generate relevant status_zone directives.

All internal variables exist and processed in runtime only, while status_zone must know its name before starting worker processes in order to be able to allocate all the required shared memory zones where the relevant metrics are stored.

my config contains multiple names under same server section.
It would be neat to be able to provide some context to status_zone directive right in place

Understood. Thanks. We will consider how Angie metrics API can be improved for this particular case in the future.
