#!/bin/bash
# session hook script; write commands here to execute on the host at the
# specified state

# Framework script for automation of log collection
# CORE enters the DATACOLLECT state following the completion of a CORE session
# Logs, packet captures, configuration files, etc are still available within
# CORE nodes (LXC containers) in a persistent state.  A datacollect_hook script
# can be used to capture experiment results for post-processing and analysis.

# 1. Each session is logged in the datacollect.log
# 2. The script collects experiment results by session PID and records data about
#    experiment run that has completed.
# 3. Script goes node by node and collects logs and packet captures in the
#    destination experiment results directory.
# 4. Following completion of the script, all LXC containers and data are
#    torn down and discarded.
