Distributed tracing for Ruby

Distributed tracing shows a request as one trace across every service it passed through. AppSignal for Ruby does this for the integrations below. You do not have to pass anything between your services.

​

HTTP clients

Requests made with these libraries carry the current trace to the service being called:

• Excon
• Faraday
• HTTP.rb
• Net::HTTP

​

HTTP servers

Requests that arrive carrying a trace continue it:

• Grape
• Hanami
• Padrino
• Rack
• Rails
• Sinatra
• Webmachine

​

Background jobs

Jobs run in the same trace as the code that enqueued them:

• Active Job
• Delayed Job
• Que
• Resque
• Shoryuken
• Sidekiq

How the trace reaches a job differs per library. Each integration’s page describes its own behavior and limits.
