Author: Alexander Rebrikov at http://fastvps.ru/

Building patched nginx version on Debian Squeeze:

apt-get update
# Build packages needed for building Debian packages
apt-get install -y dpkg-dev devscripts build-essential fakeroot
# Install dependency's for building nginx
apt-get build-dep -y nginx
# Additional dependency for nginx 0.7
apt-get install -y dpatch libgeoip-dev
# Go to safe directory for building packages
cd /usr/src
apt-get source nginx

# make patch
dpkg-source -x nginx_0.7.67-3+squeeze3.dsc

export VERSION=0.7.67
cd nginx-$VERSION

# make fullstats patch
wget https://raw.github.com/FastVPSEestiOu/nginx-extended-statistics-path/master/nginx_stats.patch
patch -p1 < nginx_stats.patch


# Build nginx
debuild -us -uc # -us unsigned source, -uc unsigned changes

# Install nginx:
dpkg -i /usr/src/nginx_0.7.67-3+squeeze3_amd64.deb 

# Lock package for preventing upgrade to non patched version from repo
echo "nginx hold" | dpkg --set-selections

After that, you need add special location to any server for getting nginx statistics:

location /nginx_status {
    full_status on; 
} 

After that, you can see detailed statistics for every virtual host on this server
vihost				requests		active_time(msec)		traf
client1.shared.ru			18			0				6355
samedomain.com				22			2			8713

Fields in statistics:

• Requests is total count of requests served by nginx for certain vhosts.
• Active time is total time which nginx use for serving this vhosts. I think, it's very strange metric, use with care.
• Traf is total traffic for this vhost.

FAQ:

• Could you provide version for newest nginx release? Sorry, we can't. Please take a look on fork button.
• This patch is tested deeply? Yes, this patch work few years on 2 heavy loaded servers with thousands of vhosts without any problems.
• What is requests/active_time and traf?
