Name

opstack - produce callgraph symbol summaries

Synopsis

opstack [ options ] [profile specification]

Description

opstack outputs binary callgraph symbol summaries. Currently, this requires an x86-based box and a 2.6 kernel patch; see http://oprofile.sf.net/patches/.

Options

--accumulated / -c

Accumulate sample and percentage counts in the symbol list.
--debug-info / -g: Show source file and line for each symbol.
--demangle=none|smart|normal: none: no demangling. normal: use default demangler (default) smart: use pattern-matching to make C++ symbol demangling more readable.
--show-address / -w: Show each symbol's VMA address.
--no-header: Don't output a header detailing profiling parameters.
--long-filenames / -l: Output full paths instead of basenames.
--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.
--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.
--merge / -m [lib,cpu,tid,tgid,unitmask,all]: Merge any profiles separated in a --separate session.
--threshold / -t [percentage]: Only output data for symbols that have more than the given percentage of total samples.
