With several other trace tools being implemented for the kernel, there
is a great problem with consistencies among these tool. It is my
opinion that trace are of very little use to _most_ people with out the
availability of post-processing tools to analyses these trace. While I
wont say that we need one all powerful solution, it would be good if all
solutions would at least be able to talk to the same post-processing
facilities in user-space. Before LTTng is even considered into the
kernel, there need to be discussion to determine if the trace mechanism
being propose is suitable for all people interested in doing trace
analysis. The fact the there also exist tool like LKET and LKST seem to
suggest that there other things to be considered when it comes to
implementing a trace mechanism that everyone would be happy with.

It would also be useful for all the trace tool to implement the same
probe points so that post-processing tools can be interchanged between
the various trace implementations.
