Uptime.com Check Types | How to Build the Ultimate Uptime Monitoring System
How much infrastructure for a domain or application can fail before the customer starts to notice? What about before your productivity is affected? The answer to these questions will help you fully utilize uptime monitoring. Here are just a few examples of services that can be monitored for better piece of mind:
- External payment processors
- API resources
- Email servers
- VoIP protocols for support or chat
- Streaming or gaming servers
- Registration pages
- Best selling products
Your uptime monitoring system is most effective when your checks run regularly, pinging multiple pieces of infrastructure. When you have multiple checks pinging the same infrastructure from different locations, you get better detection rates and faster, more precise alert data. Here are a few ways you can group checks together for better results:
- Domain Health
- Site Speed and Efficiency
- Network Performance Monitoring
You should consider the complexity of your website, and of the existing check types for your account to get the best results. We’ll dive into some examples next.

Domain Health: Check HTTP/S Errors and Secure the Domain
Let’s begin with a Domain Health Check. You can run one with our free tool and configure each of these checks in minutes. The first check most users configure is the HTTP/S Check, which monitors a specific URL for uptime and checks that the status code is “200” or “OK.” It has some optional features that enhance what it can do.
HTTP/S Checks | Domain Monitoring Enhanced
HTTP/S checks run at one minute intervals, and mimic some of the functionality you might find in an API check. As a result, you can do more than simply check whether a URL is status 200 or not.
For example, you can test for specific pieces of code or expected strings. With this functionality, an HTTP/S check can verify the presence of internal analytics, tracking pixels, or a specific response using the “string to expect” option. Uptime.com can distinguish between a regular expression and an exact match, and can trigger a failure on exact match.
SSL and DNS | Essential Domain Security Checks
Both SSL and DNS checks run once per day, and their goal is to ensure your DNS records/SSL certifications remain valid and are not in danger of expiration. DNS is the foundation to domain accessibility and a notoriously tricky type of error to diagnose and solve. Checks that monitor DNS also report any changes your DNS provider may make on their end, which helps to alert teams of potential DNS hijacking. This malicious practice is still affecting businesses, siphoning contact details with faked URLs that erode your organization’s trust.
SSL checks ensure the customer gets the safest possible shopping and browsing experience. It monitors your certificate for any changes, and alerts you when any details change (such as the Certificate Authority issuing the certificate, and the identifying information about the company it belongs to).
WHOIS Domain Expiry Checks
A WHOIS check also occurs once per day, and it provides a default advance notice of 20 days if WhoIs information changes or is in danger of expiration. WHOIS data identifies the site’s contact information, and it’s another common vector for attack. Especially for smaller and mid-sized businesses that might not privatize this data.
When this information is changed, it’s a good idea to create an escalation immediately that gets decision makers involved. Such changes may not signal any malicious behavior, but it’s important that stakeholders who can verify these changes act quickly to prevent your customer from suffering an attack.
Malware/Virus and Domain Blacklist
Malware/Virus and Domain Blacklist checks have major benefits to both usability and optimization. Google will recognize when a site passes malicious code, and will blacklist that URL until the problem is fixed. Verifying that the issue is fixed takes time and hurts search accessibility while it’s remedied.
Usability is also affected. Browsers issue dire warnings when a site is suspected of passing on malicious code, which affects trust of the URL and may turn some potential customers away for life.
Clearly, time is a factor if your site ends up on these lists. These once-per-day domain health check routinely-updated databases for the URL you specify. If it appears on any of the lists Uptime.com checks, you receive an alert immediately so you can act quickly.

Synthetic Uptime Monitoring, RUM, and Time to First Byte
The user experience is paramount to everything you do. If your site takes too long to load, its major components don’t work, and users can’t navigate it well, you’re going to lose customers fast. Uptime monitoring should provide peace of mind that your userbase is getting the best possible experience as you grow.
Transaction Checks for Goal Funnel Analysis
Transaction checks provide some advanced functionality that simulates the user experience. They utilize a multi-step HTTP/S check to interact with elements on a website. You may have noticed the basic HTTP/S check cannot wait for an expected response, it can only view what’s on the URL you’ve designated. With a Transaction Check, it’s possible to monitor shopping carts or signup forms from the first step to the “Thank You” page.
Remember: Transaction checks run in 5-minute intervals. Use them to monitor specific goal funnels, but supplement them with HTTP/S and other infrastructure checks at regular intervals. You will trigger alerts much faster, and receive accurate technical data one which portions of your infrastructure might be down.
Combine Transaction Checks with RUM
A Real User Monitoring (RUM) Check measures the user experience of specific goal funnels, and your site as a whole. When combined with a Synthetic monitoring, you gain powerful insights into real user behavior of a specific goal funnel.
A RUM check provides advanced metrics that break down load time by page, device, specific path and more. These advanced metrics provide not only indications of the average real user’s experience, they alert contacts when load times exceed expectations you define.
Clever RUM check users will use data accumulated over time to adjust the threshold for page load times, a value (measured in seconds). Lowering this value alerts your team to potential issues with latency or performance, with a baseline accepted value based on optimal conversion and bounce rates.
Another commonly utilized check is the Speed Test. A Speed Test will provide a Waterfall containing a visualization of each element, and the length of time it took to load. This graph tells you at a glance which elements are consuming the most resources.
Both RUM and Speed Test checks tell you how long it takes for the user to see something, known as First Render in RUM. The Speed Test is global, however, so you can pick and choose a single location or test from across the globe. If you want to get a feel for what customers in a specific city are experiencing, the Speed Test is one of the fastest ways you have to get that data.
The Speed Test isn’t just a measurement of whether it’s working, rather how is it working? How are the changes your team is making to the site or application impacting your real users? Is the experience slower after a deployment? Use the Speed Test history feature to review past reports. Catching small opportunities to improve the user experience is just as important as monitoring for outages.
Network Performance Monitoring to Detect Unexpected Outages
Unexpected outages either occur outside of our infrastructure (IE a payment processor going down), or something we didn’t plan for or consider initially. Take a moment to see if anything in this list applies to you.
ICMP is a useful check when you want to look at a particular service’s availability. You might use it to monitor your payment gateway so you have first notice if you can’t accept payments. You can also ping external services critical to communication, like Slack or GitHub, to be sure the resources you need are accessible.
ICMP is not critical to your infrastructure, but it has its uses. You can use it to ping your internal infrastructure as well, ensuring traffic delivery is functioning well and providing an external notification if something goes down. Properly configured, this downtime alert would go to SMS or some other external form of communication accessible outside the corporate network.
Server and Application Monitoring for Complete Protection
There’s a lot to monitor server side to be sure application delivery is as quick as it can be, and always on. The Uptime.com API Check uses multiple HTTP/S Check steps to quickly ping resources using a mix of GET and POST requests. You can review status codes, expected strings, post URL encoded data, and issue OAuth tokens for safer access.
Remember to add extra failsafes into your API check so you can verify functionality.
