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
