健康检查端点

概述

实现健康检查端点，用于监控服务健康状况、依赖项以及是否准备好接收流量。

使用场景

Kubernetes 存活性和就绪性探针
负载均衡器健康检查
服务发现与注册
监控和告警系统
熔断器决策
自动扩缩容触发器
部署验证

快速开始

最小工作示例：

import express from "express";
import { Pool } from "pg";
import Redis from "ioredis";

interface HealthStatus {
  status: "healthy" | "degraded" | "unhealthy";
  timestamp: string;
  uptime: number;
  checks: Record<string, CheckResult>;
  version?: string;
  environment?: string;
}

interface CheckResult {
  status: "pass" | "fail" | "warn";
  time: number;
  output?: string;
  error?: string;
}

class HealthCheckService {
  private startTime = Date.now();
  private version = process.env.APP_VERSION || "1.0.0";
  private environment = process.env.NODE_ENV || "development";

// ... (完整实现请参阅参考指南)

Health Check Endpoints

Overview

Implement health check endpoints to monitor service health, dependencies, and readiness for traffic.

When to Use

Kubernetes liveness and readiness probes
Load balancer health checks
Service discovery and registration
Monitoring and alerting systems
Circuit breaker decisions
Auto-scaling triggers
Deployment verification

Quick Start

Minimal working example:

import express from "express";
import { Pool } from "pg";
import Redis from "ioredis";

interface HealthStatus {
  status: "healthy" | "degraded" | "unhealthy";
  timestamp: string;
  uptime: number;
  checks: Record<string, CheckResult>;
  version?: string;
  environment?: string;
}

interface CheckResult {
  status: "pass" | "fail" | "warn";
  time: number;
  output?: string;
  error?: string;
}

class HealthCheckService {
  private startTime = Date.now();
  private version = process.env.APP_VERSION || "1.0.0";
  private environment = process.env.NODE_ENV || "development";

// ... (see reference guides for full implementation)

Best Practices

✅ DO

Implement separate liveness and readiness probes
Keep liveness probes lightweight
Check critical dependencies in readiness
Return appropriate HTTP status codes
Include response time metrics
Set reasonable timeouts
Cache health check results briefly
Include version and environment info
Monitor health check failures

❌ DON'T

Make liveness probes check dependencies
Return 200 for failed health checks
Take too long to respond
Skip important dependency checks
Expose sensitive information
Ignore health check failures
