This is a semantic question. (I''m doing some technical writing about DTrace.) I''ll little confused about how to explain what an "action" is. By any definition, "trace(x);" is an action. However, what about just "i++;"? Looking at the DTrace guide page 76: "Probe actions are described by a list of statements separated by semicolons (;)

As of patch 32953 dtrace support is in bleadperl (5.11.0). The probes are based on Alan Burlinson''s original blog post on the subject: http://blogs.sun.com/alanbur/date/20050909 By guarding the probes with PERL_SUB_*_ENABLED the performance hit is unmeasurable. All the necessary bits already existed in the wild. I just assembled them and made the necessary changes to

Hi, I need help in calculating Java method time-stamp in following fashion. Consider following method example. long method3(long stop) { try { Thread.sleep(1500); } catch (Exception e) { } //////////////////// real CPU intensive operation /////////////////////////// for (int i = 1; i < stop; i++) { stop = stop * stop * i; };

Hello, The Hotspot JVM Runtime group would like to put forth a project proposal to improve the capabilities of DTrace''s ustack()/jstack() actions to better handle non-standard user stack frames. This email will describe the background, the problem, and our proposed solution. We''re interested in getting a sponsor for this work to help us with the process of getting the

Hi all i want to view the stack trace of the real time java application using DTrace probes. i am using jrts provider for finding the information of real time threads.
