[nickvido]

fuzzlog_analyzer.py

Analyzes libFuzzer/OSS-Fuzz logs to extract key information and surface actionable findings.

Features:

• Tracks fuzzer execution stats (runtime, exec/s, corpus growth)
• Detects crashes, timeouts, OOMs, and sanitizer findings
• Identifies artifact locations and interesting coverage discoveries
• Provides both human-readable and JSON output formats

Usage:

python3 fuzzlog_analyzer.py <log_file_paths...> [options]

Options:

• --json: Output results in JSON format instead of human-readable text
• --max-funcs N: Maximum NEW_FUNC lines to display per file (default: 10)

Examples:

# Analyze a single log file
python3 fuzzlog_analyzer.py fuzzer_run.txt

# Analyze multiple log files with JSON output
python3 fuzzlog_analyzer.py *.txt --json

# Limit NEW_FUNC output
python3 fuzzlog_analyzer.py fuzzer_run.txt --max-funcs 5
