How To Use Oprofile Linux
session containing sample files Now a while ago, I had a similar problem and was able to run it using the suggestions made here: http://marc.info/?l=oprofile-list&m=124113612205853&w=2 But now, I just can't get any output. I tried opcontrol --dump too. My oprofiled.log has the following message: Nr. sample dumps: 8 Nr. non-backtrace samples: 74704 Nr. kernel samples: 69812 Nr. lost samples (no kernel/user): 0 Nr. lost kernel samples: 0 Nr. incomplete code structs: 0 Nr. samples lost due to sample file open failure: 0 Nr. samples lost due to no permanent mapping: 0 Nr. event lost due to buffer overflow: 0 Nr. samples lost due to no mapping: 0 Nr. backtraces skipped due to no file mapping: 0 Nr. samples lost due to no mm: 10 Nr. samples lost cpu buffer overflow: 56952 Nr. samples received: 76080 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 148676 Nr. samples received: 166162 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 30466 Nr. samples received: 50220 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 39925 Nr. samples received: 59094 Nr. backtrace aborted: 0 Any help, please?

I removed /root/.oprofile, so it was created in the default state. Just no samples to be found. Comment 1 Chuck Ebbert 2007-05-01 19:34:51 EDT Please post contents of /proc/cpuinfo (just one CPU not all.) Did this work with earlier kernels on this exact hardware? Comment 2 Daryll 2007-05-01 19:42:03 EDT Yes, it worked with the latest FC6 kernel. That's why I was so surprised when nothing happened. :) processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 mode
