• Quadrennial (!) DTrace unconference started in 2008

• ~1 VC Entrepreneur-in-Residence
• Twitter: #dtraceconf
• Thanks to our sponsors, Joyent — and the FIPP!
• Huge thanks to Ryan Wilson, Brittany Berry and Jenny Miller from
DTrace since 2012: Core
• Added new ways of representing aggregated data via “agghist,”
“aggpack,” and “aggzoom” options
• Added new json() subroutine
• Added DTrace userland CTF support
• Added the new (on-by-default!) “temporal” option
• Added print() support for translated types
• Added support for fds, curpsinfo, sched and proc providers
in a zone container
DTrace since 2012: Platforms
• FreeBSD implemented the pid provider in 9.0 and, as of 9.2,
enabled DTrace by default!
• NetBSD added DTrace support — including support for ARM!
• Linux port of DTrace largely completed by Oracle — but keeping
the user-level portion proprietary has limited its impact
DTrace in 2016 and beyond
• Distributed systems are ubiquitous and tracing in distributed
systems has improved tremendously; how can DTrace help?
• Instrumenting multi-processes applications via the pid provider is
still painful; can we improve?
• The rise (resurrection?) of statically compiled languages like Go
and Rust presents new opportunity — and new challenges
• DTrace and serverless computing?
• User-level postmortem tracing?
• Anti-roadmap: Dynamic translators?
