Phoronix: KTAP: A New Dynamic Tracing Tool For Linux
KTAP is an experimental project that's a new dynamic tracing tool for Linux. KTAP has several different design principles from SystemTap, one of the current most common dynamic instrumentation and tracing tools for Linux. This new project might satisfy some of those developers that have been wanting Sun/Oracle's DTrace to come to Linux...
DTrace is available on FreeBSD, Mac OS X, Oracle Linux and Solaris. I doubt that a project aiming to fulfill the same role on Linux will gain wide acceptance unless it aspires for Linux to be one of many platforms that it supports.
