Computer Science Seminar Series
Solaris Dynamic Tracing (DTrace)
September 19, 3:00pm
Weir Hall, Room 235
Presenter: James Mauro
DTrace is a revolutionary technology implemented in Solaris 10 that provides for dynamically instrumenting both the Solaris kernel and unmodified application binaries through the use of probe insertion in the execution path. DTrace provides a powerful and safe framework for gaining visibility into the behavior of your system at the workload and kernel level. Using DTrace in Solaris and OpenSolaris allows users, developers, administrators, etc, to gain an unprecedented level of understanding of their workloads and how they interact with the underlying operating system.
In this talk, we will provide and overview of DTrace, look at some of the implementation details, and examples of using DTrace across a variety of scenarios.
