access log off nginx not working?

  • 772

I have the following drop.conf files located in /etc/nginx/drop.conf

# if you don't like seeing all the errors for missing favicon.ico requests
# sent by a lot of browsers in root we dont need to log these - they mean extra IO
location = /favicon.ico { access_log off; log_not_found off; }

# if you don't like seeing errors for a missing robots.txt in root
# same reason as above - extra IO
location = /robots.txt { allow all; access_log off; log_not_found off; }

location = /apple-touch-icon.png { access_log off; log_not_found off; }
location = /apple-touch-icon-precomposed.png { access_log off; log_not_found off; }

# this will prevent files like .htaccess .htpassword .secret .git .svn etc from being served
# You can remove the log directives if you wish to
# log any attempts at a client trying to access a hidden file
location ~ /\. { deny all; access_log off; log_not_found off; }

# Deny access to any files with a .php extension in the uploads directory
location ~* ^/wp-content/uploads/.*.php$ {
    deny all;
    access_log off;
    log_not_found off;
}

# Deny access to any files with a .php extension in the uploads directory for multisite
location ~* /files/(.*).php$ {
    deny all;
    access_log off;
    log_not_found off;
}

Strange thing is when I include it in whichever server directive - ie in whichever virtual host I have configured - I'm still getting favicon logs in my access log. Is this a BUG ?? It looks like the include is simply not working ?

Example of the virtual host I'm including this in:

server {
        listen       127.0.0.1:8080;
        server_name  .somehost.com;
    root  /var/www/somehost.com;

        access_log /var/log/nginx/somehost.com-access.nginx.log main;
    error_log  /var/log/nginx/somehost.com-error.nginx.log;

        location ~* \.php.$ {
        # Proxy all requests with an URI ending with .php*
        # (includes PHP, PHP3, PHP4, PHP5...)
        include /etc/nginx/fastcgi.conf;
        }

        # all other files
        location / {
            root  /var/www/somehost.com;
        }

        error_page 404 /errors/404.html;
        location /errors/ {
                alias /var/www/errors/;
                internal;
        }

        #this loads custom logging configuration which disables favicon error logging
        include /etc/nginx/drop.conf;
}

yet in access logs for that domain im still seeing:

***** - - [06/Jul/2012:22:16:05 +0000]  "GET /favicon.ico HTTP/1.1" 404 134 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.47 Safari/536.11"

Yes I have restarted and reloaded nginx.

This is actually quite interesting. When I add a specific location directive directly to the virtual host above and disable the include favicon.ico requests ARE STILL being logged. ie. I comment in include bit and add the following to the above virtual host:

#include /etc/nginx/drop.conf;
location = /favicon.ico { access_log off; log_not_found off; }

Very strange.

  1. I would put the drop.conf earlier in the conf (just after the root directive).

    Also make sure to reload or restart nginx so that it's using the new configuration.

  2. I was looking at the same problem, the favicon 404 generates a subrequest AFAIK, subrequests do not inherit settings of the location they were called from. My solution for excluding logging of 404 (and other) responses is something like this:

    location = /favicon.ico 
{ 
    log_not_found off; 
    log_subrequest off; 
    access_log off; 
    error_page 404 /404notlogged.html; 
    try_files $uri =404; 
} 

location = /404notlogged.html 
{ 
    expires +1y; 
    log_not_found off; 
    log_subrequest off; 
    access_log off; 
    internal; 
}
