Ruby client for Datadog API v1.3.2

The Ruby client is a library suitable for inclusion in existing Ruby projects or for development of standalone scripts. It provides an abstraction on top of Datadog's raw HTTP interface for reporting events and metrics.

What's new?


  • Support an aggregation key to aggregate events together


  • Metrics can be counters, rather than just gauges (thanks to @treeder)

  • Metrics can be tagged.



  • You can now manage host tags

  • You can now get event details and query the stream in addition to posting events

  • Functionality relating to events with a duration has been deprecated

  • The underlying clients have been updated to use Datadog's new public HTTP API


  • You do not need to use environment variables anymore to use the client.


From Source

Available at:

$ cd dogapi-rb
$ rake gem
$ gem install pkg/dogapi-*.gem

Using RubyGems

Gem page:

$ gem install dogapi

If you get a permission error, you might need to run the install process with sudo:

$ sudo gem install dogapi

If you get a LoadError, missing mkmf, you need to install the development packages for ruby.

$ # on ubuntu e.g.
$ sudo apt-get install ruby-dev


How to find your API and application keys

Go to your setup page.

A word about hosts and devices

Events and metric data points can be attached to hosts to take advantage of automatic tagging with the host's tags.

If you want to attach events and points to a specific device on a host, simply specify the device when calling emit functions.

Submit an event to Datadog

require 'rubygems'
require 'dogapi'

api_key = "abcdef123456"

# submitting events doesn't require an application_key, so we don't bother setting it
dog =

dog.emit_event('Testing done, FTW'), :host => "my_host")

Tag a host in Datadog

require 'rubygems'
require 'dogapi'

api_key = "abcdef123456"
application_key = "fedcba654321"

dog =, application_key)

dog.add_tags("my_host", ["tagA", "tagB"])

Submit a metric to Datadog

You want to track a new metric called and have just sampled it from my_device on my_host. Its value is 50. Here is how you submit the value to Datadog.

require 'rubygems'
require 'dogapi'

api_key = "abcdef123456"

# submitting metrics doesn't require an application_key, so we don't bother setting it
dog =

dog.emit_point('', 50.0, :host => "my_host", :device => "my_device")

Let us now assume that you have sampled the metric multiple times and you would like to submit the results. You can use the emit_points method (instead of emit_point). Since you are submitting more than one data point you will need to pass a list of Time, float pairs, instead of a simple float value.

require 'rubygems'
require 'dogapi'

# Actual sampling takes place
t1 =
val1 = 50.0

# some time elapses
t2 =
val2 = 51.0

# some more time elapses
t3 =
val3 = -60.0

api_key = "abcdef123456"

dog =

dog.emit_points('', [[t1, val1], [t2, val2], [t3, val3]], :host => "my_host", :device => "my_device")
