CAN-FD DoS Analyzer

This repository contains a Python tool designed to parse automotive Controller Area Network with Flexible Data-Rate (CAN-FD) log files. It identifies failed test cases, calculates Denial of Service (DoS) times based on message timestamps, and outputs the results for further analysis.

Features

• Parses CAN-FD log files with potential inconsistencies or tester comments.
• Identifies failed test cases automatically.
• Calculates DoS times for each failed test case.
• Outputs results to a file for persistent record-keeping.

Requirements

• Python 3.x
• No external libraries required (uses standard Python libraries like json and datetime).

Usage

1. Clone the repository:

git clone https://github.com/adriancamaj/can-fd-dos-analyzer.git

2. Navigate to the project directory:

cd can-fd-dos-analyzer

3. Place your log file in the project directory: Ensure your log file is named inputFile.log or update the file_path variable in main.py accordingly.

4. Run the script:

python main.py

5. View the results: The DoS times for failed test cases will be output to dosFile.log in the project directory.

Example Output

Test case #5 - DoS time is: 0:00:55.357000

• dosFile.log: The output file containing DoS times for failed test cases.
• parse_log.json: Intermediate JSON file containing parsed log records.
• case_verdicts.json: Intermediate JSON file containing case verdicts and comments.

Project Structure

• main.py: The main script that orchestrates the parsing and analysis.
• log_parse.py: Contains functions for parsing the log file, identifying failed test cases, calculating DoS times, and outputting results.
• inputFile.log: The log file to be parsed (not included; user must provide).

How It Works

1. Parsing the Log File:

   • Reads the log file line by line.
   • Cleans and splits each line into identifiable components.
   • Stores the data in a list of dictionaries for easy access.

2. Identifying Failed Test Cases:

   • Scans for test cases marked as "Failed".
   • Extracts the case numbers of failed tests.

3. Calculating DoS Times:

   • For each failed test case, finds the start time (when the problematic message was sent) and the end time (when the response was received).
   • Calculates the DoS time by subtracting the start time from the end time.
   • Compiles the results into a readable format.

4. Outputting Results:

   • Writes the DoS times for all failed test cases to dosFile.log.
