After you have created a free account on Cloudradar, navigate to Dashboard and click the CREATE WEBSITE MONITORING button.
A dialog will pop up where you can paste in the URL of the site you need to monitor. The protocol can be selected manually or it’ll auto-select from the URL you paste in. Click the CREATE button and you’re done.
In this one simple step you created a host and a website monitoring check. Of course you can now add more checks, define a path, an expected string and much more. You’ll see all these options by clicking on the Add checks panel.
Almost every website must be accessed by its hostname and not by its IP-address. The reason for that is the so-called virtual hosts. A single web-server can serve thousands of websites using a single IP-address. A web server knows that a site is being accessed by a domain name instead of an IP-address and jumps into the right virtual host for that domain.
But also if you access your webserver by IP-address you can tell the web server which virtual hosts (web site) is requested by specifying a header called "host". If you access your site by encrypted https a technology called SNI (Server Name Indication) is used.
If you monitor your webserver by its IP-address you can monitor all web sites (virtual hosts) without entering all domains as separated hosts. Create a Website Check for the host monitored by the IP-address. Click on
ADD CUSTOM HEADER. Enter
Host as the header name and the domain of your web site as the header value. If the selected protocol is https SNI is used automatically.
