Gregg & Mauro, DTrace: Dynamic Tracing in Oracle Solaris, Mac OS X and FreeBSD | Pearson
Not only that, but because the low-level details of each operating system’s kernel and IO libraries can vary, the book takes you through specific cases of where problems differ on Solaris, OSX and FreeBSD. Books by Brendan Gregg. Margus Haavala marked it as to-read May 21, Other providers include the fbtor functional boundary trace, which allows calls to kernel-level functions to be intercepted, timed and aggregated.
Using DTrace Chapter 3: Although it’s possible to write to global storage, this can lead to race conditions and data loss if competing threads write out at the same time. There are no discussion topics on this book yet.

Update company size to: Use DTrace in the application and database development process. It’s worth noting that the authors explicitly recommend against profiling on a 1s basis, and instead suggest profiling dtrce Hz or Hz to ensure that regular system-wide processes which might be scheduled at a 1s period don’t skew the results seen over a short running DTrace script.
Many of these take the form of trying to answer a specific problem, giving not only an answer but also a feel of how one can go about solving similar problems in the future. Laust marked it as to-read Jan 06, On the other hand, programs can also have probes compiled in.

However, it’s more common for a DTrace script to collect data; either timings or textual data.
Unlike other approaches for tracing where the trace points are compiled in or not whether or not they are debug modeDTrace probes use dynamic code replacement.
