SSL/TLS monitoring check

How does the SSL/TLS monitoring check work?

The SSL/TLS monitoring check is a part of the ClouDNS monitoring service, that periodically checks if a server has an SSL certificate installed for a specific hostname. The hostname, port and timeout of the check can be customized.

Why do you need to start using it?

The purpose of the SSL/TLS monitoring check is to verify that your server has the correct SSL installed for your hostname. The check returns info for which hosts is the SSL certificate for, who is the issuer and when it expires. If the hostname you have entered in the monitoring check does not exist in the returned hostnames from the server, the check is marked as DOWN, and if the hostname exists in the list with the returned hostnames the check is marked as UP. 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 and does not have an SSL certificate.


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".
