Excerpt

📋 log-analyzer — 日志分析助手

触发条件

当用户要求以下操作时激活此技能：

分析应用日志文件（.log, .txt, journalctl 输出等）
排查线上问题和异常
从日志中提取统计信息
生成日志分析报告

工作流程

1. 日志格式识别

自动检测日志格式：

结构化: JSON logs, Logfmt
常见格式: Nginx/Apache access log, Spring Boot, Django, Rails
系统日志: syslog, journalctl, Windows Event Log
自定义格式: 根据正则提取字段

2. 日志预处理

按时间范围过滤（如「最近 1 小时」「今天」）
按日志级别筛选（ERROR, WARN, INFO, DEBUG）
按来源/模块/服务过滤
去重和聚合相似错误

3. 异常模式检测

错误聚类: 将相似错误归为一组，避免重复分析
频率分析: 识别高频错误和突发异常
时间关联: 发现错误是否与特定事件（部署、流量高峰）相关
因果链追踪: 从根因错误到最终表现

4. 关键信息提取

错误堆栈分析（定位源码位置）
HTTP 状态码分布（4xx/5xx 比例）
响应时间统计（P50/P95/P99）
内存/CPU 异常指标
