OPREPORT(1)              General Commands Manual             OPREPORT(1)

NAME         top

       opreport - produce symbol or binary image summaries

SYNOPSIS         top

       opreport [ options ] [profile specification]

DESCRIPTION         top

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

OPTIONS         top

       --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.
