Session Logs - 会话日志分析

激活词: 会话日志 / 搜索历史 / 历史记录

功能

• 搜索历史会话
• 分析会话模式
• 提取关键信息
• 按时间过滤

Python实现

import json
import os
from datetime import datetime, timedelta
from pathlib import Path

class SessionLogs:
    def __init__(self, log_dir: str = "~/.openclaw/logs"):
        self.log_dir = Path(log_dir).expanduser()

    def list_sessions(self, days: int = 7) -> list:
        sessions = []
        cutoff = datetime.now() - timedelta(days=days)

        for file in self.log_dir.glob("*.log"):
            mtime = datetime.fromtimestamp(file.stat().st_mtime)
            if mtime > cutoff:
                sessions.append({
                    'file': file.name,
                    'modified': mtime,
                    'size': file.stat().st_size
                })

        return sorted(sessions, key=lambda x: x['modified'], reverse=True)

    def search_logs(self, keyword: str, days: int = 7) -> list:
        results = []
        for file in self.log_dir.glob("*.log"):
            try:
                with open(file, 'r', encoding='utf-8', errors='ignore') as f:
                    for i, line in enumerate(f, 1):
                        if keyword.lower() in line.lower():
                            results.append({
                                'file': file.name,
                                'line': i,
                                'content': line.strip()[:200]
                            })
            except:
                pass
        return results

    def extract_commands(self, log_file: str) -> list:
        commands = []
        with open(self.log_dir / log_file, 'r') as f:
            for line in f:
                if 'command:' in line.lower() or 'user:' in line.lower():
                    commands.append(line.strip())
        return commands

使用示例

logs = SessionLogs()

# 列出最近7天会话
recent = logs.list_sessions(7)
for s in recent:
    print(f"{s['modified']}: {s['file']}")

# 搜索关键词
results = logs.search_logs("Python", days=30)
for r in results:
    print(f"{r['file']}:{r['line']}: {r['content']}")

输出格式
