Cron Evaluator

Cron Evaluator

Evaluates cron job 健康 across 4 pillars: Temporal, Resource, Resilience, and Pertinence.

4 Pillars Pillar 检查s Score Range Temporal Midnight collision, frequency, jitter 0-1 Resource Heavy commands (torch, docker, ollama) 0-1 Resilience 记录ging, flock, timeout, error handling 0-1 Pertinence Cron vs 系统d timer recommendation 0-1 Usage # 扫描 all cron jobs python3 cron_evaluator_v3.py --扫描

# 运行 健康 检查 python3 cron_evaluator_v3.py --健康

# 获取 improvement suggestions python3 cron_evaluator_v3.py --suggest

健康 Thresholds Score 状态 >80% 🟢 健康Y 60-80% 🟡 NEEDS_WORK <60% 🔴 CRITICAL Key 检查s Temporal Collision 检测ion # Two crons at 00:00 → suggest jitter if cron1['time'] == '0 0 ' and cron2['time'] == '0 0 ': suggest("添加 jitter: sleep $((RANDOM % 60))")

Resource 签名atures HEAVY_COMMANDS = ['torch', 'tensorflow', 'ollama', 'docker'] if any(h in command for h in HEAVY_COMMANDS): score -= 0.3 # Heavy resource consumer

Resilience Verification 检查S = { '记录ging': '>> /var/记录/...' in command or '2>' in command, 'flock': 'flock' in command, 'timeout': 'timeout' in command, 'error_handling': '||' in command }

Jitter Implementation # BEFORE (collision risk) 0 2 /path/to/script.sh

# AFTER (staggered with jitter) 0 2 sleep $((RANDOM % 60)) && /path/to/script.sh

KAN 模型

The Cron KAN (16→32→16→8→4→3) predicts cron job 质量 from 16 features 提取ed from schedule and command patterns.
