Well, I run it all over the place with no problem. I usually set it up
only on localhost

server {
listen 127.0.0.1:80 default;
server_name localhost;
root /var/www;

access_log /var/log/nginx/localhost.access.log;
error_log /var/log/nginx/localhost.error.log;

location ~ /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
}

( in /etc/nginx/conf.d/stub, or /etc/nginx/sites-available/stub,
symlinked to ../sites-enabled/stub depending on preference ) and restart
nginx.

Then test this bit works...

$ wget -O - http://localhost/nginx_status 2> /dev/null
Active connections: 1
server accepts handled requests
67892 67892 70215
Reading: 0 Writing: 1 Waiting: 0

Some os's seem to like

[nginx*]
env.url http://localhost/nginx_status

added to /etc/munin/plugin-conf.d/munin_node

then

munin-run nginx_status

should run just fine.
