$upstream_addr is returning blank

Server NGINX

Hello,

I want to access the value of $upstream_addr. Below is the code,

location / {

echo "up = $upstream_addr";

}

The response is just "up = " . What could be the reason for this?

The $upstream_addr variable keeps the addresses of the servers that were
contacted during request processing. So, if there aren’t any at the
moment of evaluation of the variable, then it will be empty.

Thanks Valentin V. Bartenev !!

I was using it before the line

proxy_pass http://xyz.com

After placing the code after proxy_pass, I am able to see the values…

Regards,
Sunny
