Also, one more thing what i observed is if i do not enable the statedump, i am able to get the trace dump, which i can view in lttv-gui. But that doesnt give any details on the process name ... Is there anything i am missing ?? I followed the foll procedure : 1. downloaded and patched the lttng 0.232 version on 2.6.35.7 2. built the kernel and lttng modules and the ltt-control modules. 3. installed the modules on target. 4. then loaded all the required modules 5. started ltt-armall 6. exported the lttd path 7. then executed lttctl to create trace 8. after collecting the trace (without statedump) from the target onto my pc, i am able to view that trace in lttv on my computer. -- Regards, Murali
