Dynamic tracing was open sourced in 2005 as part of opening Solaris 10. Since that time, many operating system platforms (including FreeBSD and Mac OS X) have ported DTrace facilities into their operating systems. But less well known is that numerous programming languages including the three target languages for this talk: Python, Perl and Erlang have DTrace facilities.
During this talk, we’ll cover some of the basics of DTrace itself, including its scripting language “d”, the support facilities for DTrace in Python, Perl and Erlang in each language, and finish with examples of using DTrace probes to pinpoint and resolve real-world application level problems.
