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.
To support all Datadog HTTP APIs, a generated library is available which will expose all the endpoints: datadog-api-client-ruby.
See CHANGELOG.md for details

$ cd dogapi-rb $ bundle $ rake install
Gem page: rubygems.org/gems/dogapi
$ 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
This project currently works with Ruby versions 1.9.3+
Note Newer features and new endpoint support may no longer support EOL Ruby versions but the client should still intialize and allow metric/event submission.
Go to your setup page.
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.
require 'rubygems' require 'dogapi' api_key = "abcdef123456" application_key = "fedcba654321" # by default the API Url will be set to https://api.datadoghq.com dog = Dogapi::Client.new(api_key, application_key) p dog.datadog_host # prints https://api.datadoghq.com # API Url can be passed to the initializer... dog = Dogapi::Client.new(api_key, application_key, nil, nil, nil, nil, 'https://myproxy.local') p dog.datadog_host # prints https://myproxy.local # ...or set on the client instance directly dog = Dogapi::Client.new(api_key, application_key) dog.datadog_host = 'https://myproxy.local' p dog.datadog_host # prints https://myproxy.local # in any case, contents of the DATADOG_HOST env var take precedence ENV['DATADOG_HOST'] = https://myproxy.local dog = Dogapi::Client.new(api_key, application_key) p dog.datadog_host # prints https://myproxy.local
require 'rubygems' require 'dogapi' api_key = "abcdef123456" # submitting events doesn't require an application_key, so we don't bother setting it dog = Dogapi::Client.new(api_key) dog.emit_event(Dogapi::Event.new('Testing done, FTW'), :host => "my_host")
require 'rubygems' require 'dogapi' api_key = "abcdef123456" application_key = "fedcba654321" dog = Dogapi::Client.new(api_key, application_key) dog.add_tags("my_host", ["tagA", "tagB"])
You want to track a new metric called some.metric.name 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 = Dogapi::Client.new(api_key) dog.emit_point('some.metric.name', 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 = Time.now val1 = 50.0 # some time elapses t2 = Time.now val2 = 51.0 # some more time elapses t3 = Time.now val3 = -60.0 api_key = "abcdef123456" dog = Dogapi::Client.new(api_key) dog.emit_points('some.metric.name', [[t1, val1], [t2, val2], [t3, val3]], :host => "my_host", :device => "my_device")
If you want to specify the metric type, using the example above you can pass in a symbol key with :type and a value of a metric type such as counter, gauge or rate.
dog.emit_points('some.metric.name', [[t1, val1], [t2, val2], [t3, val3]], :host => "my_host", :device => "my_device", :type => 'counter' )
If you want to add metric tags, using the example above you can pass in a symbol key with :tags and an array of tags.
dog.emit_points('some.metric.name', [[t1, val1], [t2, val2], [t3, val3]], :host => "my_host", :device => "my_device", :tags => ['frontend', 'app:webserver'] )
require 'rubygems' require 'dogapi' api_key = "abcd123" application_key = "brec1252" dog = Dogapi::Client.new(api_key, application_key) # get points from the last hour from = Time.now - 3600 to = Time.now query = 'sum:metric.count{*}.as_count()' dog.get_points(query, from, to)
