Library for event tracing using a dtrace, note returns a dummy provider if not available.
Simple library for event tracing using a number of other libraries which can be enabled or disabled as required.
The aim of this library is to provide a simple way of integrating dtrace or alternatively log based tracing within a node.js javascript library.
Install the module with: npm install dtracer
This library will optionally load the dtrace provider and provides a number of utility methods for adding and firing probes.
The default tracer is accessible through the tracer module directly.
var dtracer = require('dtracer')
// configures an application with DTrace used as the default provider
dtracer
.addProbe("startChild", "int", "char*")
.addProbe("stopChild", "int", "char*")
.addProbe("onExit", "int", "char*")
tracer.enable()
tracer.probes.startChild(123, "cool new child") // fire a probe with the previously specified parameters
Note: As per limitations with the node-dtrace-provider you only get 6 arguments per probe to play with, so choose wisely.

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.
