opentelemetry-common gem provides common helpers for OpenTelemetry.
What is OpenTelemetry?
OpenTelemetry is an open source observability framework, providing a general-purpose API, SDK, and related tools required for the instrumentation of cloud-native software, frameworks, and libraries.
OpenTelemetry provides a single set of APIs, libraries, agents, and collector services to capture distributed traces and metrics from your application. You can analyze them using Prometheus, Jaeger, and other observability tools.
How does this gem fit in?
opentelemetry-common gem provides common helpers for semantic conventions, context propagation patterns, etc. It depends only on the OpenTelemetry Ruby API, not the SDK.
How do I get started?
Install the gem using:
gem install opentelemetry-common
Or, if you use Bundler, include
opentelemetry-common in your
require 'opentelemetry/common' # TODO: example of semantic convention helpers # Context propagation in Net::HTTP client OpenTelemetry::Common::HTTP::ClientContext.with_attributes('peer.service' => 'example') do Net::HTTP.get('example.com', '/index.html') end # Context propagation in Net::HTTP instrumentation attributes = OpenTelemetry::Common::HTTP::ClientContext.attributes tracer.in_span( HTTP_METHODS_TO_SPAN_NAMES[req.method], attributes: attributes.merge( 'http.method' => req.method, 'http.scheme' => USE_SSL_TO_SCHEME[use_ssl?], 'http.target' => req.path, 'peer.hostname' => @address, 'peer.port' => @port ), kind: :client ) do |span| ... end
How can I get involved?
