WHOIS is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block or an autonomous system, but is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format.
Among other things WHOIS can be used to query for domain expiry.
Netdata auto discovers hundreds of services, and for those it doesn’t turning on manual discovery is a one line configuration. For more information on configuring Netdata for WHOIS domain expiry monitoring please read the collector documentation.
Netdata has a public demo space (no login required) where you can explore different monitoring use-cases and get a feel for Netdata.
WhoIs domain expiry metrics measure the amount of time left until a domain name expires. This metric is important for tracking the health of a domain and for planning for renewals. If a domain is not renewed before it expires, it can become unavailable, leading to potential loss of revenue from customers unable to access the website or services associated with the domain.
Netdata comes with a built in alert which is triggered when there is less than 24 hours for domain expiry.
