The objective of this post is to get people up and running with SmartOS with enough development tools to do some C/C++ and NodeJS development and take advantage of some amazing tools available only on this platform.
In my case the killer app available on SmartOS is DTrace, which enables me to peak inside a running nodejs application and observe various aspects of it's operation.
In my case I normally use the VMWare version of dtrace, this can be downloaded from SmartOS Download Page.
Once downloaded this just needs to be copied to your Documents/Virtual Machines
folder and launched by double clicking on the file.
