Overview

Set up comprehensive uptime monitoring with health checks, status pages, and incident tracking to ensure visibility into service availability.

When to Use

Service availability tracking

Health check implementation

Status page creation

Incident management

SLA monitoring

Quick Start

Minimal working example:

// Node.js health check
const express = require("express");
const app = express();

app.get("/health", (req, res) => {
  res.json({
    status: "ok",
    timestamp: new Date().toISOString(),
    uptime: process.uptime(),
  });
});

app.get("/health/deep", async (req, res) => {
  const health = {
    status: "ok",
    checks: {
      database: "unknown",
      cache: "unknown",
      externalApi: "unknown",
    },
  };

  try {
    const dbResult = await db.query("SELECT 1");
    health.checks.database = dbResult ? "ok" : "error";
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Implement comprehensive health checks

Check all critical dependencies

Use appropriate timeout values

Track response times

Store check history

Monitor uptime trends

Alert on status changes

Use standard HTTP status codes

❌ DON'T

Check only application process

Ignore external dependencies

Set timeouts too low

Alert on every failure

Use health checks for load balancing

Expose sensitive information
