The following is a summary of the added features : - Complete instrumentation of the kernel. - Compile-time option for kernel-support for tracing. - Configurabilty of the trace driver. Including the ability to choose which types of events to trace and to what degree of detail. - Extended configurability of the trace daemon in accordance with the configurability of the trace driver. - Lots of enhancements to the GUI front-end of LTT, including toolbar, icons for the trace graph, per-event menus, and many others. - Experimental support for SMP. - System analysis is much more advanced with details such as how much time each runing process looses waiting for I/O. - Help files. - Updated patches for most recent kernels. - Lots of other things ... Now remember, you still get to see exactly all the events occuring on a system, in the order and detail of their occurrence. Moreover, you now get more detail, more configurability and the front-end is much nicer to play around with. Most importantly, you can get information no other tool is able to provide (Like the exact time runing a task, not the estimated one as currently available through /proc, the time a task spends waiting for I/O, and real system call latency, not the sampled one as in gprof.) Everything with a total system overhead of below 1.5% ! The Linux Trace Toolkit can be found at the following address : http://www.info.polymtl.ca/~karym/trace The above page contains more detail, screenshots, documentation than a mail can carry ... Thank you for your time and hope to hear from you soon! =================================================== Karim Yaghmour karym@info.polymtl.ca Operating System Consultant (Linux kernel, real-time and distributed systems) =================================================== - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.tux.org/lkml/
