Pinned topic LTTng for PowerLinux ?

Is LTTng supported on PowerLinux?     
 
 
Is this a good long-term tool to learn and begin using?

    As far as I can tell you it works pretty fine on powerlinux, I've made some tests with LTTng on Fedora 17 ppc64 months ago. However, as of RHEL 6.3 and SLES 11.2, there isn't RPM packages for LTTng so you must build from source (straightforward though).  
     
    I strongly believe it is a good long-term tool to learn because I've seen a LTTng community pretty active and improving it even further. The toolkit is also ease to use, fast and provides several visualization tools (graphical and command-line).
     
    I am going to post in the blog my experiences with LTTng on powerlinux soon.

       Do you know if it will be supported on x86/Linux (RHEL/SUSE) as well?

         I believe so because it does already exist lttng packages for x86 on both Fedora and OpenSuSE distros.

         Lttng is not supported on RHEL / SLES (Suse Linux Enterprise Server) editions, yet. You might have to recompile your kernel on these versions to get the lttng working.

           Yes, you are right.  I did some poking around and looks like that LTTng-modules package (even the earlier 2.0 stable version) needs Linux kernel version 2.6.38 at the minimum.  RHEL 6.x comes with 2.6.32 version of the linux kernel.  So it doesn't look like it is supported for RHEL 6.  I was not able to compile lttng-modules package on RHEL 6.2 (kernel 2.6.32).  Guess we will have to wait for RHEL 7 which I believe is going to be based on Linux kernel version 3.x.

             if Fedora 17 ppc64 is an option for you then go for it. I compiled lttng (including modules) in that distro & worked fine.

            SLES11SP2 comes with 3.0 kernel.
            OBS (openSUSE Build Service) have packages, everything you need is just rebuild those packages for ppc. Either using OBS or just locally.
