As you've discovered, Apache doesn't log the request separate from the
response, so a log analyzer is no help here.
If the higher-ups are only interested in server time, as opposed to
page-load time, you can add code to the controller that keeps track of
how long it takes PHP (or whatever) to generate the response, from the
time the controller starts processing to the end. Then write the times
to a log or database. If there's not just one controller script, you
can use auto_prepend and auto_append configuration directives to
include the profiling code.
If they are interested in actual page load times in real browsers,
stops on page load, and uses an ajax request to send the results to a
tracking server. There must be 3rd party services that do this.
As you can see, very different approaches depending on what you
actually want to measure.
