You can now use IBM's DProbes with Opersys' Linux Trace Toolkit to provide a universal (dynamic) tracing capability for Linux. It is universal because it provides a common tracing mechanism for all executables whether in user or kernel space. It is dynamic because tracepoints are defined and applied dynamically to object modules as probepoints using DProbes - no source code modification is required. To use dyamic trace you will require version 1.2 of DProbes, or later from http://oss.software.ibm.com/ and LTT version 0.9.4pre4 or later from http://www.opersys.com/ The DProbes kernel patch will need to be compiled with correct configuration options to enable it to work with LTT. See the respective installation instructions in each package for more details.
