  • quickstack is a tool to take call stack

    quickstack is a tool to take call stack traces with minimal overheads.
    
    There are a couple of tools to take stack traces such as gdb, pstack, but these tools
    have serious overheads. In many cases, target process stops for 0.2-N seconds.
    So it is dangerous to use such tools in production environment.
    quickstack makes it possible to take stack traces in less than 1 milliseconds. This is
    much smaller overhead so you can frequently take stack traces in production environment.
    
    quickstack internally scans stack frames and guesses caller functions.
    For 64bit applications, it is highly recommended to build with -fno-omit-frame-pointer.
    
    How to build:
    * Install binutils 2.22+ and elfutils-libelf-devel
    * Install cmake
    * cmake .
    * make
    * make install
    
    Install dependencies (Ubuntu):
    sudo apt-get install binutils-dev
    sudo apt-get install elfutils-dev
    sudo apt-get install libiberty-dev
    
    
    Example:
    [user$] quickstack -p `pidof mysqld`
