Dynamic Tracing with DTrace and SystemTap
DTrace (http://dtrace.org/blogs/about/) is a dynamic tracing framework,
originally developed for Solaris, has been released under the CDDL
license and ported to many other Unix-like OSes including FreeBSD, OS X
and Linux.
SystemTap (https://sourceware.org/systemtap/) provides similar
functionality to DTrace but is Linux specific and released under the GPL.
Dynamic tracing tools make it possible to safely inject instrumentation
points (probes) into running applications on production environments; no
recompilation is necessary and there is only minimal performance
overhead when being used, and no overhead when not. Probes can be used
to gather performance metrics to identify bottlenecks, create aggregate
statistics such as the size distribution of filesystem writes, or to
introspect arguments passed to individual functions in a running
application without ever taking it offline.
Many will head to the Lucky Lab on Hawthorne after the meeting.
