# Stackdriver The stackdriver gem instruments a Ruby web application for Stackdriver diagnostics. When loaded, it integrates with Rails, Sinatra, or other Rack-based web frameworks to collect application diagnostic and monitoring information for your application. Specifically, this gem is a convenience package that loads the following gems: - [google-cloud-debugger](https://googleapis.dev/ruby/google-cloud-debugger/latest - [google-cloud-error_reporting](https://googleapis.dev/ruby/google-cloud-error_reporting/latest - [google-cloud-logging](https://googleapis.dev/ruby/google-cloud-logging/latest - [google-cloud-trace](https://googleapis.dev/ruby/google-cloud-trace/latest On top of that, stackdriver gem automatically activates the following instrumentation features: - [google-cloud-debugger instrumentation](https://googleapis.dev/ruby/google-cloud-debugger/latest/file.INSTRUMENTATION.html - [google-cloud-error_reporting strumentation](https://googleapis.dev/ruby/google-cloud-error_reporting/latest/file.INSTRUMENTATION.html - [google-cloud-logging instrumentation](https://googleapis.dev/ruby/google-cloud-logging/latest/file.INSTRUMENTATION.html - [google-cloud-trace instrumentation](https://googleapis.dev/ruby/google-cloud-trace/latest/file.INSTRUMENTATION.html ## Usage Instead of requiring multiple Stackdriver client library gems and explicitly load each built-in Railtie classes, now users can achieve all these through requiring this single **stackdriver** umbrella gem. ```ruby require "stackdriver" ```
