Web application uptime monitoring

Saturday, May 27th, 2017 by Servage

uptimeHigh availability and uptime have become very important for websites and applications. Solving downtime issues should be taken care of quickly to avoid losing any visitors or profit when it comes to business websites. Fortunately, there are services that monitor websites, databases and servers around the clock and inform website administrators within minutes when something is not working as expected.


Although being a pricy service, Pingdom is one of the most popular uptime monitoring services. The time it takes for Pingdom to detect that your website is down is very short, and their downtime reports are accurate. Pingdom has been said to sometimes report false positives for  downtime, but nowadays it’s possible to specify after how many failed attempts a downtime notification should be sent. This allows for a perfect balance between speed and reliability in downtime reporting.

Uptime Robot

Uptime Robot is, and promises to always be, a free monitoring service. It can be used to monitor up to 50 websites or services, such as MySQL databases, for free. Uptime Robot started as a completely free service, but since then they have added paid plans for bigger organizations who need more than 50 monitors for their infrastructure.

Uptime Robot can be used to host a public status page, which can be customized by developers thanks to their simple API.


Being released in 1999, Nagios is a rather dated-looking monitoring service. Despite the user interface looking old, Nagios is still a very popular choice for companies as their downtime monitor. What makes Nagios a little different from the other services in this list is that the Nagios Core is a self-hosted service. It takes some more effort to install and get started with Nagios, but after the initial setup, Nagios offers a secure, internal infrastructure monitor.

Many companies choose Nagios to monitor servers that cannot be accessed directly from the Internet or services that a company wants to keep private.


StatusCake is a freemium service with both free and paid plans. All of their plans come with unlimited monitors, including their free community edition, which is limited by a slower check rate. Some of the advanced features have also been disabled from the free edition, but the community edition still offers a great starting points for small websites.

The paid plans come with a 30-second check rate and multiple locations that will be used to check for downtime. This prevents false positives caused by worldwide traffic routing issues.
