Currently I am looking at `get_primary_peers` function in 
`lua-upstream-nginx-module`.

Hi!

The `get_primary_peers` also works at the worker level since the upstream group is per worker.

Thanks for the reply!

Is there a recommended way to get such information at global level?

One approach I can think of is using `ngx.shared.dict` to broadcast events to workers and workers "report" back its information.

Hi!

Maybe the upstream zone can help you? http://nginx.org/en/docs/http/ngx_http_upstream_module.html#zone

Thanks.

That looks promising. But it seems only commercial version of Nginx is able to retrieve the zone information. Apparently `lua-upstream-nginx-module` does not support it yet...
