Implement and Understand Uptime Health Check Endpoints


Uptime: Health Check Endpoint Explained

In the world of IT infrastructure and web applications, uptime is king. Even minor amounts of downtime can result in lost revenue, decreased productivity, and damage to your brand’s reputation. That’s why implementing a comprehensive uptime monitoring system should be a top priority.

But what exactly should you monitor to ensure maximum uptime for your business? One critical component is setting up a health check endpoint. This simple yet powerful feature provides immense value in maintaining smooth IT operations and identifying issues before they cause costly outages.

In this post, we’ll explore what a health check endpoint is, why it’s important, and how services like Network Notification make setting one up quick and easy. Let’s get started!

What is a Health Check Endpoint?

A health check endpoint is a unique URL that you configure to report on the status of your application, server, or website. It’s essentially a web page that returns a status code indicating whether the resource being monitored is up and running as expected.

Some common status codes you may see from a health check endpoint include:

  • 200 OK – The resource is up and operating normally.
  • 503 Service Unavailable – The resource is down or experiencing issues.
  • 429 Too Many Requests – The resource is up but overloaded.

When you set up monitoring for the health check endpoint URL, the monitoring service will make regular requests to that page. If anything other than a 200 OK status is returned, it triggers an alert so you can investigate and resolve the problem.

Why are Health Check Endpoints Important?

There are a few key reasons why health check endpoints are so valuable:

Early warning system

By monitoring a health check endpoint, you gain an early warning system for potential problems. Rather than waiting for an issue to escalate into a full outage, you can detect degraded performance and troubleshoot the cause before customers are impacted.

Monitoring from outside

Tools like Network Notification check your health endpoints from servers outside your infrastructure. This allows detecting issues that may not be apparent when monitoring internally.

Checks application status

While monitoring server resources like CPU usage is useful, health endpoints go one step further by verifying that the application itself is functioning for end users. No assumptions needed.


You can create custom health check endpoints tailored to your stack. For example, ping a database, check a cached value, or run an API call to confirm smooth operations. The possibilities are endless!

Health Check Endpoint Examples

To better understand how they work, let’s look at some real-world examples of health check endpoints:

1. Basic HTML Page

A simple HTML page that returns a 200 status code functions as a barebones health check:

<head><title>Health Check</title></head>
<body>System Up</body>

The response body text “System Up” is optional but can be useful.

2. API Health Check

For API-based applications, call a dedicated endpoint that returns system status:

GET /api/v1/health-check

“status”: “healthy”

This checks that the API itself is up and responding as expected.

3. Database Check

Connect and run a basic query against your database to verify its operational status:

GET /db-health-check

// Ping database
const db = connectToDatabase();
const results = db.query(“SELECT 1”);

if(results) {
return {status: “OK”}
} else {
return {status: “Database unreachable”}

As you can see, health endpoints provide tremendous flexibility to monitor your unique environment.

How to Set Up a Health Check aka Heart Beat Endpoint

While the examples above require custom code, services like Network Notification simplify the process drastically by handling the technical details for you. Here’s an overview of how health endpoints work with Network Notification:

1. Sign up and create a check

First, you’ll sign up for Network Notification at and create a new check.

2. Choose monitoring type

When creating the check, you’ll select the “Health Beat” monitoring type.

3. Enter endpoint URL

Next, provide the unique URL for your health check endpoint that you want to monitor. This can be anything returning an HTTP status code like the examples we covered earlier.

4. Configure check settings

Finally, you can customize settings like monitoring frequency, alert thresholds, notifications, and more. Network Notification makes it easy to fine-tune checks to fit your specific needs.

And that’s it! Within minutes you can start monitoring your custom health check endpoint with Network Notification. No coding required.

Health Check Endpoint Best Practices

To get the most value from your health check endpoints, keep these tips in mind:

  • Make it unique – Dedicate a specific URL for monitoring only, separate from public site pages.
  • Check critical components – Monitor parts like databases and caching that can cripple systems if they go down.
  • Return useful info – Having the endpoint provide insightful response codes, texts, or JSON data makes troubleshooting easier.
  • Automate it – Combine your health check endpoint with automated monitoring tools like Network Notification for round-the-clock peace of mind.
  • Test it – When making changes to your environment, verify the health endpoint still functions as expected.
