NAME
Mojolicious::Plugin::Statsd - Emit to Statsd, easy!
SYNOPSIS
# Mojolicious
$self->plugin('Statsd');
# Mojolicious::Lite
plugin 'Statsd';
# Anywhere you have Mojo helpers available
$app->stats->increment('frobs.adjusted');
# It's safe to pass around if need be
my $stats = $app->stats;
# Only sample half of the time
$stats->increment('frobs.discarded', 0.5);
# Time a code section
$stats->timing('frobnicate' => sub {
# section to be timed
});
# Or do it yourself
$stats->timing('frobnicate', $milliseconds);
# Save repetition
my $jobstats = $app->stats->with_prefix('my-special-process.');
# This becomes myapp.my-special-process.foo
$jobstats->increment('foo');
DESCRIPTION

REQUIREMENTS
This module lists the following modules as runtime dependencies:
- IO::Socket::INET
- Mojo::Base
- Mojo::Loader
- Time::HiRes
- perl version v5.16.0 or later
See the cpanfile file for the full list of prerequisites.
INSTALLATION
The latest version of this module (along with any dependencies) can be installed from CPAN with the cpan tool that is included with Perl:
cpan Mojolicious::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 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.
SECURITY CONSIDERATIONS
When using the "set_add" method, be wary of exposing sensitive information like IP addresses, usernames, email addresses or even session ids over insecure channels. One workaround is to log a message digest of the value instead, for example
use Digest::SHA qw/ hmac_sha1 /;
...
$statsd->set_key( "myapp.sessions", hmac_sha1( $session->id, $my_secret_key );
Note that the keys should be consistent across worker processes and hosts.
When generating metric names based on untrusted sources (such as HTTP requests), ensure that the metrics contain only printable characters and do not contain colons (":") or pipes ("|"), since these are used by the statsd protocol.
SUPPORT
Only the latest version of this module will be supported.
This module requires Perl v5.16 or later. Future releases may only support Perl versions that are supported by Mojolicious.
