This assists diagnosis of a performance or functional problem. SystemTap eliminates the need for the developer to go through the tedious and disruptive instrument, recompile, install, and reboot sequence that may be otherwise required to collect data.</p> <p>The recent addition of kprobes to the Linux kernel provides the needed support but is not easy to use. SystemTap provides a simple command line interface and scripting language for writing instrumentation for a live running kernel. Over time, we plan to enlarge our script "tapset" library to aid instrumentation reuse and abstraction. We also plan to support probing userspace applications. We are investigating interfacing Systemtap with similar tools such as Frysk, Oprofile and LTT.</p> <p>SystemTap is still under rapid development, so it is not appropriate to use it on production systems. However, SystemTap in its current state can still be a useful tool for developers.</p> <p>Current project members include Red Hat, IBM, Intel, and Hitachi.</p> </td> </tr> </table> </div> </div> <table cellspacing="2" cellpadding="2" border="0" width="100%"> <tr> <td align="center" class="footer"><a href= "http://sources.redhat.com/systemtap">SystemTap</a></td> </tr> </table> </body> </html>
