NAME

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

VERSION

version 0.001000

SYNOPSIS

 # in app.psgi
 use Plack::Builder;

 builder {
    enable 'AccessLog::Timed',
       format => '%r %t [%{x-time-real}o %{x-time-cpu-user}o %{x-time-cpu-sys}o]';

    enable 'ProcessTimes';

    $app
 };

DESCRIPTION

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

• X-Time-Real - Actual recorded wallclock time

• X-Time-CPU-User

• X-Time-CPU-Sys

• X-Time-CPU-CUser

• X-Time-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 -.
