Re-animator Replayer - replay DataSeries traces

Re-animator Replayer is a tracing tool that is intended for extracting traces of any program or an application and then replaying their I/O behavior. It uses DataSeries, a binary format which provides a fast and efficient way to store and analyze traces. Our trace replayer follows SNIA's specification documents -- "POSIX System-Call Trace Common Semantics" and "IO Trace Common Semantics" -- which describe the system call fields, their types, and their values.

Re-animator Replayer can be used as a benchmarking tool to measure and reproduce the I/O performance under various workloads, or for analyzing the program traces for security purposes, etc.

For more information on the Re-Animator project, please see our paper Re-Animator: Versatile High-Fidelity Storage-System Tracing and Replaying.

Re-animator Replayer is under development by Ibrahim Umit Akgun of the File Systems and Storage Lab (FSL) at Stony Brook University under Professor Erez Zadok, with assistance from Professor Geoff Kuenning at Harvey Mudd College.

Build Instructions

Requires bash.

1. Install the following required programs and libraries:

   git cmake perl autoconf automake gcc g++ libtool libboost-dev libboost-thread-dev libboost-program-options-dev build-essential libxml2-dev zlib1g-dev libaio-dev
   

   On Ubuntu 16 and 18, all the above requirements are available through the APT package manager.

2. Clone this repository and run build-reanimator-replayer.sh. This will place build files in the current directory under build/ and install the system-call-replayer and other completed binaries and libraries under reanimator_replayer_release/.

   • If invoked with build-reanimator-replayer.sh --install, the script will install include files and libraries under /usr/local/
   • You may specify custom build and install directories with the command line options --build-dir DIR and --install-dir DIR. Run ./build-reanimator-replayer.sh --help for a full list of options.

Usage
