Portland Linux/Unix Group Advanced Topics Meeting Announcement Who: Daniel Hedlund What: Dynamic Tracing with DTrace and SystemTap Where: Free Geek, 1731 SE 10th Avenue, Portland (Left Entrance) When: Tuesday, March 18th, 2014 at 7pm Why: The pursuit of technology freedom
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.
