NAME

Plack::Middleware::ProcessTimes - Include process times of a request in the Plack env

VERSION

version 1.000000

SYNOPSIS

# in app.psgi
use Plack::Builder;

builder {
   enable 'AccessLog::Structured',
      extra_field => {
        'pt.cpu-user' => 'CPU-User-Time',
        'pt.cpu-sys'  => 'CPU-Sys-Time',
      };

   enable 'ProcessTimes';

   $app
};

DESCRIPTION

Plack::Middleware::ProcessTimes defines some environment values based on the "times" in perlfunc function. The following values are defined:

• pt.real - Actual recorded wallclock time

• pt.cpu-user

• pt.cpu-sys

• pt.cpu-cuser

• pt.cpu-csys

Look up times(2) in your system manual for what these all mean.

CONFIGURATION

measure_children

Setting measure_children to true will "waitpid" in perlfunc for children so that child times can be measured. If set responses will be somewhat slower; if not set, the headers will be set to -.
