How to monitor domain expiration dates using Zabbix
It is very important to monitor multiple domain expiration dates when working for a big company. It is more useful when working with multiple registrars, even if you don’t have access to these registrars accounts.
This approach uses a Zabbix template with discovery rules to make whois queries and parse answers. You can receive expiration alerts via Email, if configured in Zabbix.
