Ruby installation instructions

Use the installation instructions below if you're installing Helios in a standard Ruby service.

Installing Helios in your Ruby microservice

Navigate to your project's root directory, and install the latest Helios OpenTelemetry SDK:

gem install helios-opentelemetry-sdk

Initializing Helios in the code

In your project's root file, paste the following code snippet:

require 'helios/opentelemetry/sdk'

Helios::OpenTelemetry::SDK.initialize(
  api_token: "<HS_TOKEN>",        # TODO: Replace value your API token.
  service_name: "<SERVICE_NAME>", # TODO: Replace value with service name.
  enable: true,                   # Defaults to false if omitted. 
  environment: "<ENV_NAME>"       # TODO: Replace value with environment name.
)

For more information about automatic and manual instrumentation with Ruby see the Opentelemetry documentation.
