| Used to analyze the chaos logs & packet captures and produce a consolidated analysis of each test attempt in a text file. |
| Look at the "Sample output" below for a sample output. |
| Requirements: Needs tshark/wireshark installed on the host machine. |
| |
| 1. Install pyshark python module on the host machine. There are couple of bug fixes that are yet to be accepted upstream for us to use the vanilla version. |
| Download the source tarball from here: https://drive.google.com/a/google.com/file/d/0B-W7uZuGgJr6QldhZm5ManROODA/view?usp=sharing |
| |
| tar xvzf pyshark.tgz |
| cd pyshark-master/src |
| python setup.py build |
| python setup.py install |
| |
| 2. Run the analyzer script from the collected log directory. |
| cd <Log Dir> |
| ./chaos_analyzer.py |
| |
| 3. The analysis output for each attempt is stored in the same folder as the packet captures with the name: chaos_analyzer_try_[0-9].log. |
| |
