Module: NewRelic::Agent::Instrumentation::Sinatra

Includes:
ControllerInstrumentation
Defined in:
lib/new_relic/agent/instrumentation/sinatra.rb

Overview

NewRelic instrumentation for Sinatra applications. Sinatra actions will appear in the UI similar to controller actions, and have breakdown charts and transaction traces.

The actions in the UI will correspond to the pattern expression used to match them. HTTP operations are not distinguished. Multiple matches will all be tracked as separate actions.
