Php – Apache – How to log the file name and size of file uploads

apache-2.2loggingPHPupload

I want to keep some statics about the files uploaded to my server, including the file name, size and response time.

I use PHP to handle the uploads in the server side (client-side is a POST form) but ideally I'd like to use Apache's logging facilities to collect the above-mentioned data. So, I'm trying to modify the default format for the access_log but I only found how to add the response time (using the %D formatter).

Is it possible to use Apache logs to monitor at least the size of POST requests and if possible the filenames of the uploaded files?

As per the Apache documentation you want %I and mod_logio:

%I  Bytes received, including request and headers, cannot be zero. You need to enable mod_logio to use this.
%O  Bytes sent, including headers, cannot be zero. You need to enable mod_logio to use this.
