  9. 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

  10. 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

  11. 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?
