opgprof - produce gprof-format profile data

SYNOPSIS

opgprof [ options ] [profile specification]

DESCRIPTION

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

--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

ENVIRONMENT
