It was originally created back in 2005 by Sun Microsystems for its proprietary Solaris Unix systems, "for troubleshooting kernel and application problems on production systems in real time," [1]explains Wikipedia . "DTrace can be used to get a global overview of a running system, such as the amount of memory, CPU time, filesystem and network resources used by the active processes," explains its Wikipedia entry.

But this week, [2]Gentoo announced :

> The real, mythical DTrace comes to Gentoo! Need to dynamically trace your kernel or userspace programs, with rainbows, ponies, and unicorns — and all entirely safely and in production?! Gentoo is now ready for that!

>

> Just emerge [3]dev-debug/dtrace and you're all set. All required kernel options are already enabled in the newest stable Gentoo distribution kernel...

>

> Documentation? Sure, there's lots of it. You can start with our [4]DTrace wiki page , the [5]DTrace for Linux page on GitHub , or the [6]original documentation for Illumos . Enjoy!
