11 Top Website Uptime Monitoring Tools to Know

Uptime is the time period when your website and all of its contents are fully functional and accessible. It is expressed as a percentage, thus if your web is up 99% of the time, you can expect more than 7 hours of downtime every month.

Downtime, as the name suggests, is when all or a portion of your service is unavailable. Disruptions result and potential customers are lost. Uptime monitors are useful for correctly logging, assessing, and informing on each downtime.

Additionally, a Google study found that even a one-second delay in your website loading time might reduce conversions by 20%.

Fortunately, there are numerous methods available for monitoring uptime, ranging from open-source to closed-source, low-cost to high-end, and pretty much anything in between. This post will cover some of the top website uptime monitoring tools to help you get started.

This service for synthetic modeling can complete full iterations of the path taken by the majority of website visitors. This is very helpful when adding new features to an existing website or while developing a new website before it is published.

Checking whether a website is accessible is another use for the Synthetics service. These uptime monitors can be used in combination with other tests, including load testing and API status checks.

Regular tests can be run from servers positioned in a variety of geographical areas all around the world. The user can also decide whether to conduct HTTP tests or browser-based testing.

If the monitored website is unavailable, the service issues an alert. This allows the technical staff to focus on other tasks and simply switch to the web server in the event of unanticipated downtime.

Better Uptime is a website availability monitor that regularly examines a site's uptime from five different locations. Ping tests and Web browser tests can both be run. You can choose between Google Chrome, Mozilla Firefox, and Apple Safari to perform your tests.

Not all of this system is automated. The testing system is manned by human operators as part of a managed service. Before telling the client if a target is down, the system retests it from two more locations.

This process is included in the service to avoid false-positive reporting and reduce the number of notifications that the client gets that might be the result of a problem with the Internet connection being utilized for the test.

Every test is recorded, and the user dashboard includes a list of every availability check. A color-coded bar on the console also displays the test results in order.

Screenshots of the failure notice that appears in a browser are used to document unsuccessful contact events. When a test fails, subscribers are notified. These alerts can be sent via Slack message, SMS, email, or phone call. The client can get in touch with the service's operators at any time.

The tests look at more than just whether Web pages are accessible. The user can specify tests to determine whether APIs and services that are triggered within website pages are accessible.

Better Uptime provides simple pricing that includes a free tier that offers free email alerts, 3-minute checks, and 10 monitors. With their pro services, which start at $30 per month, you can get unlimited phone calls, 50 monitors, and 30-second checks.

#8 Dotcom-Monitor

Dotcom-Monitor uses its cloud platform to offer several availability checks. Web Services Monitoring is the uptime availability plan offered by Dotcom-Monitor. This is one of the platform's four available plans.

The Web Services Monitoring plan primarily acts as an uptime monitor by repeatedly checking the availability of internet-based assets using the Ping protocol. The tests are conducted for HTTP and HTTPS availability; these are common techniques for verifying a website's availability.

Other experiments examine how SOAP and RESTful APIs function. Even though the pages they are on appear to still be available, if one of these activities fails, your website's main utilities may stop functioning.

A pop-up ad stopping functioning or the shopping cart not operating are two examples of faults brought on by API failure. This system can also test Web services that are XML- and JSON-based.

Your SSL certificate could have issues that you are unaware of. The fact that Google Chrome will prevent your website's pages from loading if the certificate has issues is a major drawback with SSL services. Therefore, doing routine automated checks on the SSL certificate is a crucial responsibility.

They offer 1 to 5-minute intervals, staggering 3-year data retention, SSL monitoring, API monitoring, and more with their services, which start at $19.95. Every plan offers a free 30-day trial, allowing you to try out all of its features before making a purchase.

System administrators can prevent outages by using Site24x7 to locate stressed-out hardware and software. Systems administrators can reallocate resources to prevent disaster by spotting status issues on the network, server, and in-application performance.

If there are no indicators of a potential outage, the Site24x7 inspection can determine which internet service malfunctioned.

Among other automated monitoring tools, these checks include a Domain Expiry Monitor, SSL/TLS Certificate Monitor, Ping Monitor, and Web Transaction Monitor.

The uptime monitors perform checks using a browser or an API. For each scenario, a monthly subscription fee will be charged in increments of 1,000 access attempts for browser access and 10,000 for API access.

The browser tests are more thorough and provide more information. They also provide screenshots of unsuccessful access attempts.

Each test run for both approaches is logged and timestamped. Additionally, the website manager can design unique tests and repeatedly run them through the remote Datadog test agents.

The uptime monitors track response times in addition to verifying a site's availability and each of its pages. The test results are available to the site manager in a dashboard with excellent visuals.

Failures or poor responses exceed performance standards and cause alerts to be sent. Through a machine learning process that takes into consideration elements like the dependability of the internet connection, the threshold levels are modified.
