Phase 61 — 跨组织SLA管理系统设计

版本: v2.0.0 创建日期: 2026-02-28 状态: ✅ 已实现 (v2.0.0)

---

一、模块概述

Phase 61 引入跨组织SLA管理系统,支持服务等级协议(SLA)的定义、监控、违约检测和补偿计算。

1.1 核心功能

• SLA合约管理: 合约CRUD、条款定义
• 多级SLA: 金牌/银牌/铜牌三级
• 实时监控: 可用性、响应时间、吞吐量
• 违约检测: 自动检测SLA违约
• 补偿计算: 违约补偿金自动计算

---

二、SLA级别定义

const SLA_TIERS = {
  GOLD: {
    name: "gold",
    availability: 0.999, // 99.9%
    maxResponseTime: 100, // 100ms
    minThroughput: 1000, // 1000 req/s
    compensationRate: 0.05, // 5%补偿率
  },
  SILVER: {
    name: "silver",
    availability: 0.995, // 99.5%
    maxResponseTime: 200, // 200ms
    minThroughput: 500,
    compensationRate: 0.03,
  },
  BRONZE: {
    name: "bronze",
    availability: 0.99, // 99%
    maxResponseTime: 500, // 500ms
    minThroughput: 200,
    compensationRate: 0.01,
  },
};

---

三、核心模块设计

3.1 SLA Manager

文件: desktop-app-vue/src/main/ai-engine/cowork/sla-manager.js

SLA条款:

const SLA_TERMS = {
  AVAILABILITY: "availability", // 可用性
  RESPONSE_TIME: "response_time", // 响应时间
  THROUGHPUT: "throughput", // 吞吐量
  ERROR_RATE: "error_rate", // 错误率
  DATA_ACCURACY: "data_accuracy", // 数据准确性
};

违约等级:

const VIOLATION_SEVERITY = {
  MINOR: "minor", // 轻微违约 (< 10% deviation)
  MODERATE: "moderate", // 中度违约 (10-25% deviation)
  MAJOR: "major", // 重大违约 (25-50% deviation)
  CRITICAL: "critical", // 严重违约 (> 50% deviation)
};

API方法:

class SLAManager {
  // 创建SLA合约
  async createSLA(orgId, tier, terms, duration) {}

  // 列出SLA合约
  async listSLAs(orgId) {}

  // 获取SLA指标
  async getSLAMetrics(slaId) {}

  // 检查SLA违约
  async checkViolations(slaId) {}

  // 计算补偿
  async calculateCompensation(violationId) {}

  // 生成SLA报告
  async generateReport(slaId, startDate, endDate) {}
}

---

四、数据库设计

CREATE TABLE IF NOT EXISTS sla_contracts (
  sla_id TEXT PRIMARY KEY,
  org_id TEXT NOT NULL,
  tier TEXT NOT NULL,
  terms TEXT NOT NULL,
  start_date INTEGER NOT NULL,
  end_date INTEGER NOT NULL,
  status TEXT DEFAULT 'active',
  created_at INTEGER NOT NULL,
  updated_at INTEGER NOT NULL
);

CREATE TABLE IF NOT EXISTS sla_violations (
  violation_id TEXT PRIMARY KEY,
  sla_id TEXT NOT NULL,
  term TEXT NOT NULL,
  severity TEXT NOT NULL,
  expected_value REAL NOT NULL,
  actual_value REAL NOT NULL,
  deviation_percent REAL,
  compensation_amount REAL,
  occurred_at INTEGER NOT NULL,
  resolved_at INTEGER,
  FOREIGN KEY (sla_id) REFERENCES sla_contracts(sla_id)
);

---

五、补偿计算公式

// 基础补偿
baseCompensation = monthlyFee * compensationRate;

// 违约程度调整
deviationMultiplier = Math.min(deviation / 50, 2.0);

// 最终补偿
finalCompensation = baseCompensation * deviationMultiplier * violationDuration;

---

六、IPC 接口 (5个)

const CHANNELS = [
  "sla:create-sla",
  "sla:list-slas",
  "sla:get-sla-metrics",
  "sla:get-violations",
  "sla:generate-report",
];

---

七、监控指标

实时监控的关键指标:

• 可用性 (Availability): uptime / total_time
• 平均响应时间 (Avg Response Time): sum(response_times) / count
• P95响应时间 (P95 Latency): 95百分位延迟
• 吞吐量 (Throughput): successful_requests / time_window
• 错误率 (Error Rate): failed_requests / total_requests

---

八、配置管理

sla: {
  enabled: true,
  defaultTier: 'silver',
  monitoring: {
    interval: 60000, // 1分钟监控一次
    retentionDays: 90,
  },
  violation: {
    checkInterval: 300000, // 5分钟检查一次
    alertThreshold: 'moderate',
    autoCompensate: false,
  },
  report: {
    autoGenerate: true,
    schedule: '0 0 1 * *', // 每月1号生成
  },
}
