The Web monitoring check is a part of the ClouDNS motoring service, that makes HTTP(S) requests to the given IP address. The hostname, port, and path can be customized.
The purpose of the Web check is to verify that your website is functioning appropriately for the users and to ensure website uptime and performance as expected. Our monitoring provides the ability to consistently monitor a website or server function, and observe how it responds. Users that rely on a website or an application for any kind of business will get frustrated or even stop using the application if it is not reliably available.
Each Monitoring check provides debugging option which you can use to find out where the problem comes from using Traceroute information - The traceroute command is used to determine the path between two connections. Often a connection to another device will have to go through multiple routers. The option can be found in the Monitoring check settings page on the right side of the "Uptime changes section".
