How to limit what apache writes to the log files

When apache creates entries in the log file (/var/log/httpd/www...) it includes all the pictures accessed on a web page as well as the html and other stuff.

I have a huge site with over 10 million pages and growing, and high traffic. My log file is now 2 gig and growing. 90% of the content of the log file are entries for each image downloaded per session.

Logging every little image downloaded from my site just wastes space and it is of no importance to me.

Is there any way to tell apache to omit logging images files or files of a certain type? This will reduce the size of my log file dramatically.

Thanks for your help.

The "conditional logging" in Apache might be what you're after:

From the docs:

Code:

# Mark requests from the loop-back interface

SetEnvIf Remote_Addr "127\.0\.0\.1" dontlog

# Mark requests for the robots.txt file

SetEnvIf Request_URI "^/robots\.txt$" dontlog

# Log what remains

CustomLog logs/access_log common env=!dontlog

So, you could probably add something like

Code:

SetEnvIf RequestImg "^.jpg" dontlog

maybe. Never actually tried it, but have adjusted my Apache logs before.

TB0ne, tried what you suggested but it did not work. It is still logging the images. Any other ideas? Thanks

Have you tinkered with it?

perhaps

Quote:

SetEnvIf RequestImg "^.jpg" dontlog

would only "notlog" a file called .jpg and not *.jpg?

Having not looked at it maybe something like this...

Quote:

SetEnvIf Request_URI "*.jpg$" dontlog
