Module: MetrixWire::Instrument::SourceLocation

Defined in:
lib/metrixwire/instrument/source_location.rb

Overview

Finds the nearest application caller frame (file.rb:42) for a span, so the dashboard can point at the line that issued a query / HTTP call. Skips the SDK's own frames and common vendor/stdlib paths. Best-effort — returns nil rather than throwing.
