We aim to exploit the capability of a fully open-source Linux target to go beyond performance measurements, and perhaps even serve as a programmable debugger. </p> <p>We find inspiration in <a href="http://www.sun.com/bigadmin/content/dtrace/">Sun's dtrace</a>, and <a href="kprobes/">IBM's dprobes</a>, but many technical aspects of our approach will be different. See this <a href="archpaper-0505.pdf">SystemTap architecture paper (2005-05-05 draft)</a>. </p> <h1>Get involved</h1> <p>Current project members include Red Hat, IBM, and Intel.
