NAME

WebService::DataDog - Interface to DataDog's REST API.

VERSION

Version 0.7.0

SYNOPSIS

This module allows you to interact with DataDog, a service that will "Capture metrics and events, then graph, filter, and search to see what's happening and how systems interact." This module encapsulates all the communications with the REST API provided by DataDog to offer a Perl interface to metrics, dashboards, events, alerts, etc.

Requests that write data require reporting access and require an API key. Requests that read data require full access and additionally require an application key.

        use WebService::DataDog;
        
        # Create an object to communicate with DataDog
        my $datadog = WebService::DataDog->new(
                api_key         => 'your_api_key_here',
                application_key => 'your_application_key',
        );
        
        # For metrics functions, first build a metrics object
        my $metric = $datadog->build('Metric');
        
        # To post metrics (past or present)
        # NOTE: only use 'value' OR 'data_points', but not both.

                type        => $metric_type,  # Optional - gauge|counter. Default=gauge.
                value       => $metric_value, # For posting a single data point, time 'now'
                data_points => $data_points,  # 1+ data points, with timestamps
                host        => $hostname,     # Optional - host that produced the metric

METHODS

new()

Create a new DataDog object that will be used as the interface with DataDog's API

        use WebService::DataDog;
        
        # Create an object to communicate with DataDog
        my $datadog = WebService::DataDog->new(
                api_key         => 'your_api_key_here',
                application_key => 'your_application_key',
                verbose         => 1,
        );

Creates a new object to communicate with DataDog.

Parameters:

• api_key

  DataDog API key. Found at https://app.datadoghq.com/account/settings

• application_key

  DataDog application key. Multiple keys can be generated per account. Generate/View existing at https://app.datadoghq.com/account/settings

• verbose

  Optional. Set to 1 to see debugging output of request/response interaction with DataDog service.

build()

Create a WebService::DataDog::* object with the correct connection parameters.

                # Use the factory to get a WebService::DataDog::* object with
                # the correct DataDog connection parameters.
                my $metric = $datadog->build( 'Metric' );

Parameters:

• The submodule name, such as Metric for WebService::DataDog::Metric.

verbose()

Get or set the 'verbose' property.

        my $verbose = $self->verbose();
        $self->verbose( 1 );

RUNNING TESTS

By default, only basic tests that do not require a connection to DataDog's platform are run in t/.

To run the developer tests, you will need to do the following:

• Sign up to become a DataDog customer ( if you are not already), at https://app.datadoghq.com/signup. Free trial accounts are available.

• Generate an application key at https://app.datadoghq.com/account/settings#api

You can now create a file named DataDogConfig.pm in your own directory, with the following content:

        package DataDogConfig;
        
        sub new
        {
                return
                {
                        api_key         => 'your_api_key',
                        application_key => 'your_application_key',
                        verbose         => 0, # Enable this for debugging output
                };
        }
        
        1;

You will then be able to run all the tests included in this distribution, after adding the path to DataDogConfig.pm to your library paths.
