Red Hat, the top Linux seller, has included in its latest update of Red Hat Enterprise Linux a preview version of SystemTap, software that lets computer administrators peer into some of the operating system's inner workings. The update was released last week.
The software's creators say the program was inspired by Sun Microsystems' DTrace (dynamic trace) and IBM's DProbes (dynamic probe) software.
Also included with RHEL 4 Update 2 is management software from a project called OpenPegasus. The software is an implementation of the Distributed Management Task Force's Web-based Enterprise Management (WBEM) and common information model (CIM) management functions.
