Tagged "dtrace"

I’ve done some work with DTrace and Perl, using my Devel::DTrace::Provider and Andy Armstrong’s Devel::DTrace, but there’s never been a ustack helper: because of the structure of the Perl interpreter, it’s impossible to write one – at least, in the intended manner…

With this post I’d like to introduce libusdt, a library for creating DTrace USDT providers at runtime, intended as the basis for implementing custom DTrace providers in dynamic languages, but applicable wherever the provider definition isn’t known at compile time.
