NAME         top

       opgprof - produce gprof-format profile data

SYNOPSIS         top

       opgprof [ options ] [profile specification]

DESCRIPTION         top

       opgprof outputs gprof-format profile data for a given binary
       image, from an OProfile session. See oprofile(1) for how to write
       profile specifications.

OPTIONS         top

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

       --version / -v
              Show version.

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

       --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 opgprof 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.

       --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.

       --threshold / -t [percentage]
              Only output data for symbols that have more than the given
              percentage of total samples.

       --output-filename / -o [file]
              Output to the given file instead of the default, gmon.out
