DTrace at AustinJUG Christmas Party
Mon Dec 17 13:07:00 CST 2007
Austin Java User's Group gave an impressive demonstration of DTrace on Solaris.
DTrace allows you to gather performance data on system calls, application servers, etc. without requiring re-building or even stopping and restarting the services or the kernel. I would have killed for this last year in the previous job.
While DTrace itself is open source (free'nuf?) the instrumenting support module/provider for the kernel is not there for Linux...yet. That, and the flavor of open has led to SystemTap which is a similar approach to run-time instrumenting and performance diagnosis.
There is a wiki page on profiling with SystemTap on the Nokia n800....>blink<
I wonder what golden age of which technology will impress my two-year-old when he grows old enough.
