<div><p>Thanks to <a href="http://search.cpan.org/dist/Catalyst-Stats">Catalyst::Stats</a>, it's already a breeze to profile the
time taken by requests, and last week I found myself looking for the same kind 
of profiling ability for memory usage.  A quick look around made me discover
the dynamic duo <a href="http://search.cpan.org/dist/Catalyst-Plugin-LeakTracker">Catalyst::Plugin::LeakTracker</a> and 
<a href="http://search.cpan.org/dist/Catalyst-Controller-LeakTracker">Catalyst::Controller::LeakTracker</a>, but they were not
exactly what I'm looking for.  So... say <em>hi</em> to <code>Catalyst::Plugin::MemoryUsage</code>. </p>
<p>The plugin is fairly simple, and (or so I hope) provides a good example of how
plugins can wiggle themselves at the different points of a request's
lifecycle. </p>
<h2>Writing the Plugin</h2>
<p>This plugin is all about capturing memory usage. To do that, I decided
to leverage <a href="http://search.cpan.org/dist/Memory-Usage">Memory::Usage</a>.  So my first step was to add a
<code>memory_usage</code> attribute to the application's context object:</p>
<pre class="brush: Perl">
package Catalyst::Plugin::MemoryUsage;
use strict;
use warnings;
use namespace::autoclean;
use Moose::Role;
use Memory::Usage;
has memory_usage =&gt; (
    is =&gt; 'rw',
    default =&gt; sub { Memory::Usage-&gt;new },
);
</pre>
<p>Behavior-wise, I wanted to mirror what the time profiler
already does: sets a baseline when the request begins, records a milestone
for each private action that is hit, and reports the results when the
processing of the request is done.   </p>
