h2. Session Title: Observing your application with DTrace
*Audience:* Application developers, System administrators, Database admins and System analyst
*Author:* Angelo Rajadurai
h3. Abstract
With the complexity of the deployment stack increase we have reduced observabilty. Traditional observability technics are not well suited for observing applications in production. Solaris DTrace provides introduces a brand new paradigm in solving this problem. In this session we will look get a quick introduction to DTrace. We will also conduct an in depth analysis of a popular OpenSource application deployed on the AMP stack (Apache MySQL PHP Javascript). Will will also demonstrate the use of DTrace to observe the entire application stack at the same time. This session will have a lot of demos. It is meant to be help the attendees use DTrace in their day job.
