Module: ScoutRailsProxy::Tracer

Defined in:: lib/scout_rails_proxy/tracer.rb

Overview

Contains the methods that instrument blocks of code.

When a code block is wrapped inside #instrument(metric_name):

The #instrument method pushes a StackItem onto Store#stack
When a code block is finished, #instrument pops the last item off the stack and verifies it’s the StackItem we created earlier.
Once verified, the metrics for the recording session are merged into the in-memory Store#metric_hash. The current scope is also set for the metric (if Thread::current isn’t nil).
