# opstack(1)

produce callgraph symbol summaries

## 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 / -f**

  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.\

- **--verbose / -V \[options\]**

  Give verbose debugging output.\

- **--version / -v**

  Show version.

## ENVIRONMENT

No special environment variables are recognised by opstack.

## FILES

- */var/lib/oprofile/samples/*

  The location of the generated sample files.

## VERSION
