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">architecture paper <font size="-1"><i>(2005-05-05 draft)</i></font></a> or this <a href="systemtap-ols.pdf">related paper</a> presented at <a href="http://www.linuxsymposium.org/2005/">OLS 2005</a> (proceedings vol. 2). An <a href="RH2_Systemtap_OLS_2005.odp"> OpenOffice 2 presentation</a> and a <a href="RH2_Systemtap_OLS_2005.pdf"> PDF</a> of the slides are also available. </p> <h1>Get involved</h1> <p>Current project members include Red Hat, IBM, and Intel.

SystemTap is expected to use kprobes as a lower layer. See its <a href="kprobes-status.html">porting status matrix</a>. </p> <h1>Documentation</h1> <p> Check out William Cohen's <a href="http://www.redhat.com/magazine/011sep05/features/systemtap/">SystemTap article</a> published in <a href="http://www.redhat.com/magazine">Red Hat's Online Magazine</a>. </p> <p> Consult the <a href="stap.html">SystemTap man pages</a>. </p> <p> The SystemTap Runtime is a collection of code that the translator uses. It eases the task of aggregating data collected from kprobes.
