Next Windows release will include DTrace support

The forthcoming Windows 10 feature update will bring support for DTrace, the open source debugging and diagnostic tracing tool originally built for Solaris. The port was announced at the Ignite conference last year, and today the instructions, binaries, and source code are now available.

DTrace lets developers and administrators get a detailed look at what their system is doing: they can track kernel function calls, examine properties of running processes, and probe drivers. DTrace commands use the DTrace scripting language, with which users can specify which information is probed, and how to report that information.

After its initial Solaris release, DTrace spread to a wide range of other Unix-like operating systems. Today, it’s available for Linux, FreeBSD, NetBSD, and macOS. The original Solaris code was released under Sun’s Common Development and Distribution License. Microsoft has ported the CDDL portions of DTrace and built an additional driver for Windows that performs some of the system-monitoring roles. The latter driver will ship with Windows; the CDDL parts are all a separate download.
