Combine Server Logs or Split

Apache and virtual Host

[ukgimp]

Are there any serious pros and cons to the performance depending on the method of logging server activity. Is it best to combine the requests and insert a %v then use a log splitter or just use a separate file for each. Combining would make a difference if you had clients who wanted their own stats.

Is it possible to mix and match so that all my sites combine and anybody elses do not.

OK No joy on that one then.

How about this for a format. I wish to capture the query string that is used to find the page. Do I need the %q or does the referer do that. Or is the %q for internal query strings?

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\" %q" commontest
