67	access_log with variables in filename does not work	Andrey Lyarskiy	somebody	"Original config:
log_format  combined_time '$remote_addr - $remote_user - $proxy_host $upstream_addr [$time_local] '
                          '""$request"" $status $body_bytes_sent $request_time';

server {
...
access_log  /var/log/nginx/$host.access.log  combined_time;
...
}

Nginx does not creating new log files, and does not write logs access logs at all.

Changing to:
access_log  /var/log/nginx/testing.access.log  combined_time;

Log file successfully created.

Changing to:
set $site test1;
access_log  /var/log/nginx/$site.access.log  combined_time;

And again no files created and no access logs at all.
