From 23eb39e9dd2ad7eb35a46fb4a3bfdd9b03d3e53c Mon Sep 17 00:00:00 2001 From: gongshengxuan Date: Tue, 16 Dec 2025 13:53:53 +0800 Subject: [PATCH 1/2] =?UTF-8?q?feat:=20=E6=96=B0=E5=A2=9E=E5=91=8A?= =?UTF-8?q?=E8=AD=A6=E5=8E=BB=E9=87=8D=E5=92=8C=E8=81=9A=E5=90=88=E6=9C=BA?= =?UTF-8?q?=E5=88=B6?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ✨ 新功能: - 告警去重功能：基于指纹识别重复告警，支持时间窗口和计数阈值 - 告警聚合功能：将相似告警聚合成组，减少告警噪音 - 统一告警处理器：集成去重和聚合功能到现有告警流程 - Web管理接口：提供RESTful API进行配置和监控 🔧 核心组件: - AlertProcessor: 统一告警处理器 - AlertDeduplicator: 告警去重管理器 - AlertAggregator: 告警聚合管理器 - AlertNormalizer: 告警标准化转换器 - DeduplicationController/AggregationController: Web管理接口 📊 数据模型: - alert_deduplication: 去重记录表 - alert_aggregation: 聚合记录表 - 内存缓存 + 数据库持久化 🧪 测试覆盖: - 单元测试: 去重和聚合核心功能 - 集成测试: 告警处理器完整流程 - API测试: Web接口功能验证 🔗 集成点: - Prometheus告警处理流程 - 现有数据库和ORM - Beego路由和控制器 ✅ 验证通过: - 去重功能正常工作（重复告警被抑制） - 聚合功能正常工作（相似告警被聚合） - API接口正常响应 - 数据库记录正确创建和更新- --- conf/dedup_example.conf | 70 ++++
