The closest thing available is a combination of mod_status and 
Apache::Status.  If you haven't tried these yet, give them a shot.  They 
provide a good deal of information.

I'm not sure what the equivalent for other operating systems is, but
here's a Solaris tip for the archives... we use /usr/proc/bin/pmap to
determine memory consumption:

  for p in `pgrep httpd`; do /usr/proc/bin/pmap -x $p | tail -1; done

pmap gives you the total memory usage, amount actually resident, amount
shared, and the amount not shared (private).

Have you seen mod_status?  It produces parsable output; you can get nice
useful info like:

You might also want to check out Apache::VMonitor. From the module's
description: "This module emulates the reporting functionalities of top(1),
extended for mod_perl processes, mount(1), and df(1) utilities. It has a
visual alerting capabilities and configurable automatic refresh mode. All
the sections can be shown/hidden dynamically through the web interface."
