# CONFIGURATION

## report

If true, the memory usage is reported automatically (at debug level)
at the end of the request.  

Defaults to true if we are in debugging mode,
false otherwise.

## action\_milestones

If true, automatically adds milestones for each action, as seen in the
DESCRIPTION.  

Defaults to true if we are in debugging mode,
false otherwise.

# METHODS

## `memory_usage()`

Returns the [Memory::Usage](https://metacpan.org/pod/Memory::Usage) object available to the context.

To record more measure points for the memory profiling, use the `record()`
method of that object:

```perl
sub foo :Path {
    my ( $self, $c) = @_;

    ...

    big_stuff();

    $c->memory_usage->record( "done with big_stuff()" );

    ...
}
```

## `reset_memory_usage()`

Discards the current `Memory::Usage` object, along with its recorded data,
and replaces it by a shiny new one.

# BUGS AND LIMITATIONS

`Memory::Usage`, which is the module `Catalyst::Plugin::MemoryUsage` relies
on to get its statistics, only work for Linux-based platforms. Consequently,
for the time being `Catalyst::Plugin::MemoryUsage` only work on Linux and
NetBSD. This being said, patches are most welcome. :-)
