check_expiration_rdap

Project Notes

Checks how far is a domain from expiring. Uses the Registration Data Access Protocol (RDAP, supporting Bootstrap), does NOT use whois. INSTALLATION DEPENDENCIES: pip3 install requests nagiosplugin Works with many ccTLDs such as Argentina. It is compatible with a large number of TLDs. Allows to indicate warning/critical days-to-expiration ranges. By default CRITICAL < 15 days, WARNING < 30 days. NOTE: I only tested with Nagios 3.x - If someone tests with other versions please let me know. Also, the rdap expiration event timestamp is split at the 'T' marker, thus ignoring time, date or timezone for expiration-today calculation this might introduce an error. I suggest running this plugin with these settings to avoid any potential bans from excessive rdap calls: define service{ use generic-service host_name localhost service_description EXPIRATION example.net check_command check_rdap_expire!example.net check_interval 1440 ; Server are checked every 1 day when in OK state retry_interval 180 ; Server checked every 3 hours if in problem state max_check_attempts 3 ; Server checked 3 times to determine if its Up or Down state } define command{ command_name check_rdap_expire command_line /usr/local/bin/check_rdap_expire $ARG1$ } replace example.net and /usr/local/bin/check_rdap_expire according to your installation path.
