```

# DESCRIPTION

This plugin will log [Catalyst](https://metacpan.org/pod/Catalyst) timing statistics to statsd.

## CONFIGURATION

```perl
__PACKAGE__->config(

  'Plugin::Statsd' => {
      disable_stats_report => 0,
  },

);
```

## `disable_stats_report`

Enabling stats will also log a table of statistics to the Catalyst
log.  If you do not want this, then set `disable_stats_report`
to true.

Note that if you are modifying the `log_stats` method or using
another plugin that does this, then this may interfere with that if
you disable the stats report.

This defaults to

```
!$c->debug
```

# INSTALLATION

The latest version of this module (along with any dependencies) can be installed from [CPAN](https://www.cpan.org) with the `cpan` tool that is included with Perl:

```
cpan Catalyst::Plugin::Statsd
```

You can also extract the distribution archive and install this module (along with any dependencies):

```
cpan .
```

You can also install this module manually using the following commands:

```
perl Makefile.PL
make
make test
make install
```

If you are working with the source repository, then it may not have a `Makefile.PL` file.  But you can use the [Dist::Zilla](https://dzil.org/) tool in anger to build and install this module:

```
dzil build
dzil test
dzil install --install-command="cpan ."
```

For more information, see [How to install CPAN modules](https://www.cpan.org/modules/INSTALL.html).

# SECURITY CONSIDERATIONS

If the ["statsd\_client"](#statsd_client) does not have a secure communications channel to the
statsd server, then there is the risk that information such as IP
addresses or session ids will be leaked.

Anything that needs to log information in a set that contains
personally identifiable information, authentication tokens or other
sensitive data should use the `psgix.monitor.statsd_secure_set_add`
function instead of the client's `set_add` method, for example:

```perl
if (my $secure_set_add = $c->req->env->{'psgix.monitor.statsd_secure_set_add'}) {
    $secure_set_add->( $c->body_param->{name_of_sheep} );
}
```

# SUPPORT
