opreport(1)


NAME

   opreport - produce symbol or binary image summaries

SYNOPSIS

   opreport [ options ] [profile specification]

DESCRIPTION

   opreport  outputs  binary  image  summaries,  or  per-symbol data, from
   OProfile profiling sessions. See oprofile(1) for how to  write  profile
   specifications.

OPTIONS

   --accumulated / -a
          Accumulate sample and percentage counts in the symbol list.

   --debug-info / -g
          Show source file and line for each symbol.

   --demangle / -D none|smart|normal
          none:  no  demangling.  normal:  use default demangler (default)
          smart: use pattern-matching to make C++ symbol  demangling  more
          readable.

   --callgraph / -c
          Show call graph information if available.

   --details / -d
          Show per-instruction details for all selected symbols.

   --exclude-dependent / -x
          Do not include application-specific images for libraries, kernel
          modules and the kernel. This option  only  makes  sense  if  the
          profile session used --separate.

   --exclude-symbols / -e [symbols]
          Exclude all the symbols in the given comma-separated list.

   --global-percent / -%
          Make all percentages relative to the whole profile.

   --help / -? / --usage
          Show help message.

   --image-path / -p [paths]
          Comma-separated list of additional paths to search for binaries.
          This is needed to find modules in kernels 2.6 and upwards.

   --root / -R [path]
          A path to a filesystem to search for additional binaries.

   --include-symbols / -i [symbols]
          Only include symbols in the given comma-separated list.

   --long-filenames / -f
          Output full paths instead of basenames.

   --merge / -m [lib,cpu,tid,tgid,unitmask,all]
          Merge any profiles separated in a --separate session.

   --no-header / -n
          Don't output a header detailing profiling parameters.

   --output-file / -o [file]
          Output to the given file instead of stdout.

   --reverse-sort / -r
          Reverse the sort from the default.

   --session-dir=dir_path
          Use  sample  database  from  the  specified  directory  dir_path
          instead  of  the  default  location.  If  --session-dir  is  not
          specified,  then   opreport   will   search   for   samples   in
          <current_dir>/oprofile_data  first.  If  that directory does not
          exist, the standard session-dir of /var/lib/oprofile is used.

   --show-address / -w
          Show each symbol's VMA address.

   --sort / -s [vma,sample,symbol,debug,image]
          Sort the list  of  symbols  by,  respectively,  symbol  address,
          number  of samples, symbol name, debug filename and line number,
          binary image filename.

   --symbols / -l
          List per-symbol information instead of a binary image summary.
          Usually, the total of all per-symbols samples for a given binary
          image  equals  the  summary count for the binary image (shown by
          running opreport with no options).  However, it's  possible  for
          some  sample  addresses to fall outside the range of any symbols
          for a given binary image.  In such cases, the  total  number  of
          per-symbols  samples  for  the binary image may be less than the
          summary  count  for  the  image.  Running  opreport   with   the
          --verbose=debug  option  will  display  an informational message
          when this difference is detected.  This difference is  typically
          very small and can be ignored.

   --threshold / -t [percentage]
          Only  output  data  for  symbols  that  have more than the given
          percentage of total samples. For profiles using multiple events,
          if  the threshold is reached for any event, then all sample data
          for the symbol is shown.

   --verbose / -V [options]
          Give verbose debugging output.

   --version / -v
          Show version.

   --xml / -X
          Generate XML output.

ENVIRONMENT

   No special environment variables are recognized by opreport.

FILES

   <session_dir>/samples
          The location of the generated sample files.

VERSION

   This man page is current for oprofile-1.1.0.
