Use DBI::ProfileDumper::Apache .

Quoting from the docs:

DBI::ProfileDumper::Apache - capture DBI profiling data from Apache/mod_perl

SYNOPSIS

Add this line to your httpd.conf:

         PerlSetEnv DBI_PROFILE DBI::ProfileDumper::Apache

Then restart your server. Access the code you wish to test using a web browser, then shutdown your server. This will create a set of dbi.prof.* files in your Apache log directory. Get a profiling report with dbiprof:

         dbiprof /usr/local/apache/logs/dbi.prof.*

When you're ready to perform another profiling run, delete the old files

         rm /usr/local/apache/logs/dbi.prof.*

and start again.

Additionally, if you wish to fine tune your profiling needs, see Speeding up the DBI for some examples on how to include profiling code (using DBI::Profile) in your application.
