Apache: Is it possible to set a default custom log format to be used by all vhosts

apache-2.2loggingvirtualhost

I would like to set up custom logging for my vhosts in Apache 2.2:

What I'm looking for is a way to define a custom log format (once) that I can then use as the format for all of my vhost's configs custom logs.

Can I define the log format at the top of my vhost.conf file then refer to it within each vhost directive (Or do I define it in the main httpd.conf)? — OR do I have to define it once for each vhost block?

Thanks

Are you asking just for the log format definition in one place?

In your main server config, use the LogFormat directive:

LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost_common

Note the end vhost_common is the nickname.

Then, you can specify in each vhost block to use that format for the log:

CustomLog logs/myvhost.access.log vhost_common

Try setting up a status page using mod_status. If you can get in after starting up your server you should see a page like this which shows each connection with its corresponding vhost, and URL.

If your site is so heavily flooded that you can't get in, try running netstat -nt | grep :80 or lsof -ni tcp:80 to see if one or two addresses are flooding your site and apply iptables accordingly.

Apache custom-log format with regex expression

SetEnvIf Authorization username="([^"]+)" digest_username=$1
LogFormat "%h %l %{digest_username}e %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined_with_user
CustomLog /path/to/log combined_with_user

Haven't tested, so not sure if Apache is going to choke on the quotes in the SetEnvIf (they may need escaped) - but this should be pretty close.
