NAME

Apache2::Profiler - profiles time seconds needed for every request

CONTENTS

SYNOPSIS



  <Location /cgi-bin>
  PerlInitHandler Apache2::Profiler
  </Location>



DESCRIPTION

Apache2::Profiler is a mod_perl init (and cleanup) handler to profile time taken to process one request. Profiled data is reported to the Apache Log file. It’d be useful to profile some heavy application taking a long time to proceed.

Apache2::Profiler is for mod_perl version 2.0 or later. If you are using mod_perl version 1.x, you need Apache::Profiler instead.

It uses Time::HiRes to take milliseconds, and outputs profiled data as Apache log notice level like:



  [Tue Oct  7 20:52:53 2003] [notice] [client 127.0.0.1] uri: /test.html takes 0.0648910999298096 seconds



CONFIGURATION

ProfileLongerThan


  PerlSetVar ProfileLongerThan 0.5



specifies lower limit of request time taken to profile. This example only logs requests which takes longer than 0.5 seconds. This value is set to 0 by default, which means it logs all requests.

TODO

o customizable log format (exportable to some profiling tools)
o profiles CPU time rather than gettimeofday
patches are always welcome!
