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,” 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, 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 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 DTrace wiki page, the DTrace for Linux page on GitHub, or the original documentation for Illumos. Enjoy!
