## 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:

```javascript
// 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
