Here is an excerpt of /var/lig/oprofile/oprofile.log:

Fri Nov  5 10:23:46 2004

Nr. sample dumps: 376
Nr. samples total: 10926835
Nr. kernel samples: 2294278
Nr. lost samples (no kernel/user): 0
Nr. lost kernel samples: 0
Nr. samples lost due to sample file open failure: 0
Nr. incomplete code structs: 0
Nr. event lost due to buffer overflow: 0
Nr. samples without file mapping: 28043
Nr. backtrace skipped due to no file mapping: 4294967295
Nr. samples without mm: 0
Nr. samples lost cpu buffer overflow: 0
Nr. samples lost task exit: 4294967295
Nr. samples received: 10985570
Nr. backtrace aborted: 4294967295



Several of these entries are not valid. This kernel did not have the 
backtrace patch. Several of these are:


Nr. backtrace skipped due to no file mapping: 4294967295

Nr. samples lost task exit: 4294967295

Nr. backtrace aborted: 4294967295

daemon:opd_stats.c:opd_print_stats() could be a bit smarter in what it 
prints out.
