With BrandZ, it’s now possible to use DTrace on Linux applications. For the uninitiated, DTrace is the dynamic tracing facility in OpenSolaris; it allows for systemic analysis of a scope and precision unequalled in the industry. With DTrace, administrators and developers can trace low level services like I/O and scheduling, up the system stack through kernel functions calls, system calls, and system library calls, and into applications written in C and C++ or any of a host of dynamic languages like Java, Ruby, Perl or php. One of my contributions to BrandZ was to extend DTrace support for Linux binaries executed in a branded Zone.
