NAME

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

VERSION

Version 1.0.3

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.
$metric->emit(
	name        => $metric_name,
	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
	tags        => $tag_list,     # Optional - tags associated with the metric
);

# For dashboard/timeboard functions, first build a dashboard object
my $dashboard = $datadog->build('Dashboard');

# Create a new dashboard
my $dashboard_id = $dashboard->create(
	title       => $dash_title,
	description => $dash_description,
	graphs      => $graphs,
);

# Delete a user-created dashboard that you don't need anymore
$dashboard->delete( id => $dash_id );

# To make any changes to an existing user-created dashboard:
# Specify dash_id and any combination of title, description, graphs
$dashboard->update(
	id          => $dash_id,
	title       => $dash_title,
	description => $dash_description,
	graphs      => $graphs,
);

# For event functions, first build an event object
my $event = $datadog->build('Event');

# To search the event stream
my $event_list = $event->search(
	start     => $start_time,
	end       => $end_time, # Optional - default 'now'
	priority  => $priority, # Optional - low|normal
	sources   => $sources,  # Optional - list of sources. Ex: Datadog, Github, Pingdom, Webmetrics
	tags      => $tag_list, # Optional - list of tags associated with the event
);

# Find all events in the last 48 hours.
my $event_list = $event->search(
	start => time() - ( 48 * 60 * 60 ),
);

# To get all details of a specific event
my $event_data = $event->retrieve( id => $event_id );

# To post a new event to the event stream
$event->create(
	title            => $event_title,
	text             => $event_text,  # Body/Description of the event.
	date_happened    => $timestamp,   # Optional, default "now"
	priority         => $priority,    # Optional. normal|low
	related_event_id => $event_id,    # Optional, id of aggregate event
	tags             => $tag_list,    # Optional - tags to apply to event (easy to search by)
	alert_type       => $alert_type,  # Optional. error|warning|info|success
	aggregation_key  => $agg_key,     # Optional. Arbitrary string to use for aggregation.
	source_type_name => $source_type, # Optional. nagios|hudson|jenkins|user|my apps|feed|chef|puppet|git|bitbucket|fabric|capistrano
);

# Submit a user event, with timestamp of `now`.
$event->create(
	title            => 'Test event',
	text             => 'Testing posting to event stream',
	source_type_name => 'user',
);

# For alert functions, first build an alert object
my $alert = $datadog->build('Alert');

# Get list, with details, of all alerts
my $alert_list = $alert->retrieve_all();

# Create a new alert
my $alert_id = $alert->create(
	query    => $query,      # Metric query to alert on
	name     => $alert_name, # Optional. default=dynamic, based on query
	message  => $message,    # Optional. default=None
	silenced => $boolean,    # Optional. default=0
);

# Retrieve details on a specific alert
my $alert_data = $alert->retrieve( id => $alert_id );

# Update an existing alert
$alert->update(
	id       => $alert_id,   # ID of alert to modify
	query    => $query,      # Metric query to alert on
	name     => $alert_name, # Optional.
	message  => $message,    # Optional.
	silenced => $boolean,    # Optional.
);

# Mute all alerts at once. Example usage: system maintenance.
$alert->mute_all();

# Unmute all alerts at once. Example usage: completed system maintenance.
$alert->unmute_all();

# For tag functions, first build a tag object
my $tag = $datadog->build('Tag');

# Retrieve a mapping of tags to hosts.
my $tag_host_list = $tag->retrieve_all();

# Return a list of tags for the specified host.
my $tag_list = $tag->retrieve( host => $host_name_or_id );

# Update tags for specified host.
$tag->update(
	host => $host,  # name/ID of host to modify
	tags => $tag_list, # Updated full list of tags to apply to host
);

# Add tags to specified host.
$tag->add(
	host => $host,  # name/ID of host to modify
	tags => $tag_list, # Updated full list of tags to apply to host
);

# Delete all tags from the specified host.
$tag->delete( host => $host );

# For search, first build a search object
my $search = $datadog->build('Search');

my $search_results = $search->retrieve(
	term  => $search_term,
	facet => [ 'hosts', 'metrics' ] #optional
);

# For graph snapshots, first build a graph object
my $graph = $datadog->build('Graph');

my $snapshot_url = $graph->snapshot(
	metric_query => $metric_query,
	start        => $start_timestamp,
	end          => $end_timestamp,
	event_query  => $event_query, # optional -- default=None
);

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:

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:

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.
