nor do i reject all of LTT: as i said before i like the tools, and i think its collection of trace events should be turned into systemtap markups and scripts. Furthermore, it's ringbuffer implementation looks better.

Ingo, can you please give some details of what you like in LTT ring buffer implementation. In systemtap we use standard relay interface from mainline kernel for bulk data transfer. If there is something that is good in LTT we certainly would like to use it.

NOTE: I took this thread out of huge thread and only ccing to systemtap mailing list as i am only referring to a small portion of the posting. If you think this is of interest to wider audience, please feel free to post it back to wider audience.
