In computing, SystemTap (stap) is a scripting language and tool for dynamically instrumenting running production Linux kernel-based operating systems. System administrators can use SystemTap to extract, filter and summarize data in order to enable diagnosis of complex performance or functional problems. SystemTap consists of free and open-source software and includes contributions from Red Hat, IBM, Intel, Hitachi, Oracle, and other community members.〔(A SystemTap update )〕 ==History== SystemTap debuted in 2005 in Red Hat Enterprise Linux 4 Update 2 as a technology preview.〔http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/release-notes/as-x86/RELEASE-NOTES-U2-x86-en.html〕 After four years in development, SystemTap 1.0 was released in 2009.〔http://sourceware.org/ml/systemtap/2009-q3/msg00831.html〕 SystemTap runs fully supported in all Linux distributions including RHEL / CentOS 5〔http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/html/Release_Notes/x86/ar01s03.html〕 since update 2, SLES 10,〔http://support.novell.com/techcenter/psdb/f1856527fefb7f2060aeb6907f319a09.html〕 Fedora, Debian and Ubuntu.
