Build Status

See CHANGELOG.md for changes. To suggest a feature, report a bug, or general discussion, open an issue.

Installation

First install the library:

gem install dogstatsd-ruby

Configuration

To instantiate a DogStatsd client:

# Import the library
require 'datadog/statsd'

# Create a DogStatsD client instance.
statsd = Datadog::Statsd.new('localhost', 8125)

Or if you want to connect over Unix Domain Socket:

# Connection over Unix Domain Socket
statsd = Datadog::Statsd.new(socket_path: '/path/to/socket/file')

Find a list of all the available options for your DogStatsD Client in the DogStatsD-ruby rubydoc or in the Datadog public DogStatsD documentation.

Origin detection over UDP

Origin detection is a method to detect which pod DogStatsD packets are coming from in order to add the pod's tags to the tag list.

To enable origin detection over UDP, add the following lines to your application manifest

env:
  - name: DD_ENTITY_ID
    valueFrom:
      fieldRef:
        fieldPath: metadata.uid

The DogStatsD client attaches an internal tag, entity_id. The value of this tag is the content of the DD_ENTITY_ID environment variable, which is the pod’s UID.

Usage

In order to use DogStatsD metrics, events, and Service Checks the Agent must be running and available.

Metrics

After the client is created, you can start sending custom metrics to Datadog. See the dedicated Metric Submission: DogStatsD documentation to see how to submit all supported metric types to Datadog with working code examples:

Some options are suppported when submitting metrics, like applying a Sample Rate to your metrics or tagging your metrics with your custom tags. Find all the available functions to report metrics in the DogStatsD-ruby rubydoc.

Events

After the client is created, you can start sending events to your Datadog Event Stream. See the dedicated Event Submission: DogStatsD documentation to see how to submit an event to Datadog your Event Stream.

Service Checks

After the client is created, you can start sending Service Checks to Datadog. See the dedicated Service Check Submission: DogStatsD documentation to see how to submit a Service Check to Datadog.
