Ruby Client for Datadog API¶ ↑
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?¶ ↑
See CHANGELOG.md for details
Installation¶ ↑
From Source¶ ↑
Available at: github.com/DataDog/dogapi-rb
$ cd dogapi-rb $ bundle $ rake install
Using RubyGems¶ ↑
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
Usage¶ ↑
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 = Dogapi::Client.new(api_key) dog.emit_event(Dogapi::Event.new('Testing done, FTW'), :host => "my_host")
Tag a host in Datadog¶ ↑
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"])
Submit a metric to Datadog¶ ↑
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")
Get points from a Datadog metric¶ ↑
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(from, to, query)
