Module: XRay::DTrace::Tracer

Defined in:
lib/xray/dtrace/tracer.rb

Overview

Ruby module to fire application-level Dtrace events (using ruby-probe).

This module provide a convenient and unified API abstracting different tracing implementations in Leopard Ruby VM (by Apple) and in the one provided by Joyent (dev.joyent.com/projects/ruby-dtrace). This module also provides a NOOP implementation for Ruby VMs with no DTrace support: So you can use the exact same code while developing on Linux and deploying on Solaris for instance.
