Hello! I have some questions concerning oprofile's logfile "oprofiled.log". Looking at the log above, I don't understand why the "samples lost cpu buffer overflow" is issued several times. Where can I see how many samples were actually recorded, and how many samples were actually lost? In that cas, is "Lost samples = 1514776 + 1391176"? That would be nearly as many as the "Nr. non-backtrace samples" (is that the number of overall recorded samples?) Thanks in advance! Robert Nr. sample dumps: 1770 Nr. non-backtrace samples: 2891740 Nr. kernel samples: 1455610 Nr. lost samples (no kernel/user): 0 Nr. lost kernel samples: 0 Nr. incomplete code structs: 18 Nr. samples lost due to sample file open failure: 0 Nr. samples lost due to no permanent mapping: 34 Nr. event lost due to buffer overflow: 6243466 Nr. samples lost due to no mapping: 1241 Nr. backtraces skipped due to no file mapping: 2201 Nr. samples lost due to no mm: 960 Nr. samples lost cpu buffer overflow: 0 Nr. samples received: 0 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 0 Nr. samples received: 0 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 0 Nr. samples received: 0 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 0 Nr. samples received: 0 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 0 Nr. samples received: 0 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 0 Nr. samples received: 0 Nr. backtrace aborted: 0 Nr. samples lost cpu buffer overflow: 1514776 Nr. samples received: 2825879 Nr. backtrace aborted: 39 Nr. samples lost cpu buffer overflow: 1391176 Nr. samples received: 2702601 Nr. backtrace aborted: 37 |
